Sky & Telescope Review

http://www.televue.com/engine/page.asp?ID=344

 

 

NEW SIEBERT MODULAR TELECENTRIC ZOOM BARLOW EYEPIECE - REVIEW

The Siebert Modular Telecentric Zoom Barlow comes in two varieties, an "AZ" model which provides a zooming Barlow capability of 3x-6x, and the "BZ" model which provides a Barlow range of 4x-8x (pictured). Both of these units are made for 2" focusers and have within the main 2" tube a smaller sliding tube which holds only 1.25" format eyepieces. Cost of the unit is $299US$, and  estimate it weighs in at approximately 9 to 10 ounces, or a tad lighter than a 24mm Hyperion, which weighs in at a little over 11 ounces. To vary the Barlow's power, you simply loosen the set screws on the side which holds the slide tube in place, then pull the tube upward, then re-tighten the set screws. This gives the user an infinite range of Barlow magnifications to best tune your eyepiece to the prevailing seeing conditions. To achieve the fairly significant range of magnification these units provide, more extension than the sliding tube allows is needed. Therefore, an add-on lens (a doublet), is provided that screws onto the bottom of the Barlow to extend its power zoom range.

BOB'S KNOBS!

Bob's Knobs are popular the world over.  Bob makes a number of accessories to make life easier using a telescope.  Bob's Knobs prevent the use of tools for many telescope adjustments.

 

It’s easy... just grab a Bob's Knob and turn.  You can even do it while looking through the eyepiece on most scopes. And you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

 

Some of his most popular products include:

 

Celestron Nexstar Telescopes;

Bob’s Knobs no-tools tripod bolts are available for the Celestron NexStar. These replace the factory Allen bolts so the telescope can be attached to the tripod without tools. They can also replace the factory plastic hand bolts that came with some NexStar 5 and NexStar 8 models. Our bolts are longer and have a larger knob, making installation and correct tightening much easier. The 5-point knobs are about 2.1 inches in diameter and have a non-slip surface for a secure grip. These will mount the Starizona Landing Pad without modification.

 

Meade Lightbridge 10” and 12” primary and secondary collimation knobs;

These replace factory screws so that collimation of both primary and secondary mirrors can take place without tools.  They also offer stronger primary mirror support springs for the Lightbridge 12" that will not sag like the factory springs.

 

Losmandy GM-8 and G-11 Mount no tools Tripod and Elevation Lock Knobs;

These replace factory Allen bolts so the mount can be set up and adjusted without tools.  The tripod bolts mount the GM-8 and G-11 equatorial head to the Losmandy tripod top piece.  The elevation lock bolts and washers secure the elevation adjustment on the GM-8 and G-11.  Bolts are stainless steel, and each has a plastic Tee handle that is 1-3/4" in diameter to provide adequate holding power when hand tightened.

NEW MARS MISSION LANDS THIS WEEKEND

 

NASA scientists hope to crack some of the secrets of Mars this weekend, when they will try to land a robot on the planet's unexplored arctic region.

The three-legged Phoenix Mars, with its backhoe arm, is equipped for a 90-day digging mission to examine the region, where a reservoir of ice is believed to lurk beneath the surface.

LHC "ALICE" T-SHIRTS

The LHC (Large Hadron Collider), a Particle Accelerator, hopefully goes online later this year.  There are a number of experiments planned for the facility.

 

The LHC is being funded and built in collaboration with over two thousand physicists from thirty-four countries as well as hundreds of universities and laboratories. When activated, it is theorised that the collider will produce the elusive Higgs boson, the observation of which could confirm the predictions and 'missing links' in the Standard Model of physics and could explain how other elementary particles acquire properties such as mass.  The verification of the existence of the Higgs boson would be a significant step in the search for a Grand Unified Theory, which seeks to unify all of the four fundamental forces: electromagnetism, the strong nuclear force, the weak nuclear force and gravitation.

 

Wikipedia Explanation of the LHC:

http://en.wikipedia.org/wiki/Large_Hadron_Collider

 

LHC Home Page:

http://lhc.web.cern.ch/lhc/

 

One of the experiments is called "ALICE", in which the aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected.  So what does this mean?  High speed collisions of Lead (Pb) ions will hopefully break the bonding by Gluons which hold Quarks together.  Bonded Quarks form the Protons and Neutrons of an atom.  An atom is a piece of matter which makes up all things in the universe except energy.

 

The reason for the ALICE experiment is to reproduce the conditions directly after the Big Bang (beginning of the Universe).  The study of the Quark-Gluon Plasma, as it heats up and cools down, will hopefully give us information to how particles form the matter which make up the Universe.

 

ALICE Home Page:

http://aliceinfo.cern.ch/

 

What's all this got to do with T-Shirts?  The ALICE project has released a T-Shirt for the project.  I am accepting orders for the T-Shirts so we can bring some out.  This is not a profit thing - it’s just for the T-Shirts.

 

The T-Shirts are $20AUD each.  Let us know your size and also whether you would like Round or V-Neck.  T-Shirts are White only.  The T-Shirts can be seen here:

http://aliceinfo.cern.ch/Public/aliceshirts.html

 

BOINC PARTICIPANTS FOR ALICE

Data produced by the LHC can be processed by BOINC users.

 

BOINC is a software platform for volunteer computing.  In other words, you can use your home computer as a resource, to computate data produced by various projects such as ALICE.  Other popular projects include SETI (Search for Extraterrestrial Intelligence) and Climate Prediction.

 

For more information on using Boinc:

PROGRESS ON NEW "LEGAL" 1MW GREEN LASER POINTER

We have now been able to develop a Green Laser Pointer which will produce a beam using less than 1mW through high quality of manufacturing.  The Lasers are also 2cm shorter than the standard models.

 

As light pollution determines how well a beam is produced, I will try to describe how well the new 1mW Lasers perform in various light polluted conditions.

 

10/10 Dark Skies (no light pollution) - no problems, the laser will produce a beam bright enough for pointing out stars to a person next to you.  It is bright enough to be used a Finderscope for your telescope.

 

9/10 Still Dark Skies - no problems.

 

8/10 Darkness - our local forest is fairly dark.  With no dark eye adaption, no problem seeing the beam and using it as a Finderscope.

 

8/10 Darkness - darker suburban lighting with dark eye adaption - no problem seeing the beam and using as a Finderscope.

 

7/10 Darkness - My house is located in the suburbs - I have a visible white street light 60m away, and more street lights further away.  Full-on suburbia houses are 250m from my backyard, and houses line the street opposite me, out the front.  I would call this darker than your average suburban house.  With only 10mins dark adaption, the beam can be seen when using the laser for pointing out stars to someone next to me, or use as a Finderscope.

 

5/10 Darkness - Average Suburbia - with full dark adaption.  No interruption from occasional car head lights.  Difficult to see the beam going all the way up to stars.

 

2/10 City Skies - not a hope!

 

New 1mW Green Laser Pointer for Astronomy $100AUD.

 

For those who have Light Pollution Meters (Sky Quality Meters), please contact us and we will try the laser under those conditions.  If you would like to buy a Sky Quality Meter, they are $155AUD.

OCEAN OPTICS SPECTROMETERS

Ocean Optics produces a vast range of Spectrometers.  Spectrometers amongst other things are used by Astronomers to determine the mass, age, chemical composition and many other properties of a star by observing its spectrum.

 

Stellar Spectroscopy was greatly undertaken firstly by Joseph von Fraunhofer and Angelo Secchi. They compared the spectra of different stars like Sirius, to our Sun.  The 2 different stars had different absorption lines.  Absorption lines are dark lines in a star's spectra caused by the absorption of specific frequencies by the atmosphere. In 1865 Secchi began classifying stars into spectral types.  The modern version of the stellar classification system was developed by Annie J. Cannon during the 1900s.

 

Observation of double stars gained increasing importance during the 19th century. In 1834, Friedrich Bessel observed changes in the proper motion of the star Sirius, which gave rise to a hidden companion star. Edward Pickering discovered the first spectroscopic binary in 1899.  He observed the periodic splitting of the spectral lines of the star Mizar over a 104 day period.

 

Spectrometers can be used on many objects with greater success as CCD technology improves.  A more affordable Spectrometer for amateur astronomers and schools is the Red Tide Spectrometer.  The Red Tide Spectrometer is a low-cost, small footprint lab spectrometer that's ideal as a general purpose instrument for amateurs, budget conscious teaching and research labs. The Red Tide has a wavelength range of 350-1000 nm, and utilizes a detector with 650 active pixels; that’s 650 data points in one full spectrum, or one data point per nanometer. Configured with a 25 µm entrance slit, the Red Tide offers ~2.0 nm optical resolution (FWHM).

 

The Red Tide is a preconfigured, off the shelf spectrometer where all of the optical bench options, such as grating and entrance slit size, are already selected. The Red Tide can be used with various Ocean Optics spectrometer accessories, light sources and sampling optics, to create application specific systems for various absorbance, reflection and emission applications. With its small footprint (89.1 mm x 63.3 mm), convenient USB interface, and integration times as fast as 3 milliseconds, the Red Tide is a great tool for basic lab measurements.

SKYSHED POD OBSERVATORY UPDATE

There has been a lot of ummming... and arrring... about ordering the SkyShed Pods.  It has been shown, by sales to the UK, that the SkyShed Pods are very slow to move until the first shipment arrives, and people can see exactly what they are getting.  The same scenario seems to be here as well.  Getting the commitments for the first container load has been difficult, with only half a container being filled so far.  Here are some extra reasons for committing to the first shipment container of Sky Shed Pods:

 

- first container load customers will receive a 5% discount on the current price list.

- first container load customers will receive a 5% discount on the delivery to their location.  Delivery price is based on half the amount quoted by Toll Ipec Road, to anyone in the eastern states below Gladstone.

- first container load customers will receive a further 3% discount due to the Australian Dollar staying stable, above 90 cents.

- I want mine, and I want it now!  ;-)

SKYSHED POD OBSERVATORIES

LATEST NEWS -

There is now a new optional Black Liner for the POD Bay.  In a two step molding process, an additional 15 lbs (7 Kilos) of virgin black polyethylene is melded to the inside of the outer POD Bay wall, forming one wall lined in black.

This extra weight creates an even stronger, thicker walled POD Bay, providing extremely high Infrared radiation protection. Hi IR protection means the POD Bay will stay cooler in temperatures over 100 F.

 

We can now give accurate quotes for the SkyShed Pod Observatories and now able to accept orders for the SkyShed Pods.

 

Contact us for the price list.  Please supply your contact details and delivery address.  We will quote a price including delivery.

 

YOUR DETAILS

Please forward us the details of the SkyShed Pod you want:

 

- model

- dome colour

- wall colour

- number of shelves

 

http://www.skyshedpod.com/

 

DELIVERY

We'll drop the Pods off ourselves, to the eastern states only (Brisbane, Sydney and Melbourne at this stage), to help save on shipping costs.  I expect the interstate shipping costs to be halved based on a quote from Toll/Ipec from Adelaide to Brisbane of $1100 for the Standard POD and $1300 for the XL-3 Pod.

 

You can of course pick up the Pod yourself.

 

NEW ZEALAND BUYERS

New Zealand buyers need to supply the same details above.  A separate way of supply and delivery needs to be completed.  I will let you know the options soon.  The price list in AUD$ remains the same at this stage.  We are considering a number of delivery options for New Zealand which will keep the prices to a minimum.  I believe this would be best done once the PODs arrive here, and we can see what we have to work with.

 

New Zealand buyers please note - the payment options below are for Australia only.  I will forward the NZ payment options on request.

 

PAYMENT

Payment will need to be upfront for this particular product.  A pre-order 50% deposit will be needed, with the remanding 50% to be paid once the shipment is ready to set sail from the USA!  Usually 5-6 weeks at sea, then I pass them through customs etc.

 

A shipping container needs to be filled before shipment.

 

 

NEW "LEGAL" 1MW GREEN LASER POINTER

Most states in Australia have updated, adapted or legislated new laws for owning a Green Laser Pointer.  The laws basically state, a 1mW (milli-watts) or less power output is legal.  Greater than 1mW, in most states, requires permission from the Commissioner of Police - call your local Police Firearms Dept.  You may need to have a good reason to own a laser greater than 1mW.  South Australia (my state) still has no procedures in applying for permission for the more powerful than 1mW Lasers.  There is a new system for classifying the lasers and their outputs.  Most people are aware of the older system as showing the Class II Laser (<1mW) & Class III (>5mW) Lasers.

 

The most popular size for use in astronomy has been the 5mW Class IIIa Laser Pointers.  It works well even in the suburbs and is powerful enough to show a larger crowd, in a darker location.  Exceptions to this is when the Moon is out, washing out the night sky.  Observatories and the like organistions, still hold sky tours when the Moon is out.  In this case, a more powerful laser is needed and the 20mW is most suitable.

 

We are currently trialing a 1mW Laser (legal throughout Australia) to be available for astronomy.  Ensuring the quality, and modifying the make up of the laser, has improved the brightness of the beam.  This Laser will be best serving astronomers who use them as FinderScopes, as well as pointing out objects to someone next to you.

 

Benefits of the new 1mW Laser include:

 

- cheaper price (less than a 5mW)

- longer battery life

- more durable

- legal

 

Let us know if you are interested and we'll keep you posted.

 

Beware of crap lasers!

AUTOCOLLIMATORS - NEW PRICING

Using an Autocollimator is the most accurate way of collimating a Newtonian telescope.  It is far more accurate than using a Laser Collimator.  Owning a 16" F/4.5 Reflector, I find them invaluable.  Accuracy on a short focal ratio telescope is crucial.

 

To Understand how the autocollimator is used, consider the following analogy:

 

A fun house has two mirrors facing each other in a room.  One of the mirrors can be moved by using a lever in the center of the room.  If you stand in the center of the room and look in one mirror, you will see your reflection.  If the two mirrors are not exactly parallel, you will also see a reflection of your reflection in the other mirror.  These reflections will go on for what seems forever, creating a line of ever smaller images of yourself.  When the mirrors are parallel, you will only see your reflection in the mirror because your body is blocking the reflection from the other mirror.  Suppose another person is looking through a small hole in the fixed mirror.  This hole is centered on the position where you are standing.  When the mirros are slightly out of parallel, he sees you and a series of reflections of you in the mirror behind you from his perspective.  When both mirrors are parallel, he sees only you and no reflections.

 

If a flat mirror is placed in the focuser of a Newtonian telescope and it has a small hole placed in it to look through, the center of the primary along with secondary and the mirror in the autocollimator act like the two mirrors in the example.  When a Newtonian is properly collimated, all the multiple reflections will appear as one.

 

A standard collimator or laser is used first to get the rough alignment.

 

Light Pipe/Site Tube Combination $65AUD
AutoCollimator $65AUD

HIGH RESOLUTION SPECTROGRAPH FOR THE AMATEUR

The LHIRES III Spectrograph is already used by dozens of amateur astronomers around the world.  It is used by associations for public shows and for scientific projects.  University students around the world are trained using the LHIRES III.

 

This high resolution spectrograph allow us to visually watch the solar spectra with a lot of fine details. This is an ideal instrument for clubs and association who organize astronomy days for the public - always interested to better understand messages from the light.

Lhires III spectrograph has been designed for small telescope (typically 8" f/10 telescope) and is then perfectly adapted for backyard astronomy. It can be setup in numerous instruments and you can use several type of CCD camera, webcam, or SLR cameras to record your own spectra.

The LHIRES III is also a perfect tool for studying the sky. Students from several universities are learning from this spectrograph. Its design is powerful but simple and one can easily open it to see inside. Assembling the spectrograph is also very educational. Easy to use, it allows practical astrophysic on small telescope.

 

Without telescope, it allow to watch, safely, the solar spectra in very high resolution.

With a video camera or a webcam and a small instrument, Lhires III becomes a spectro-heliograph. One can then image the Sun in multiple wavelength (Ha, HeI, K...) using a scanning technic.

$4330AUD

NOVOSIBRISK - RUSSIAN TELESCOPES

The Novosibirsk web site has been hijacked and currently contains a virus.  Please avoid!  Hopefully already fixed.

 

 

LAST  CHANCE  TO REGISTER  FOR  THE  VicSouth STAR  PARTY

The VicSouth Annual Star Party is on again this coming weekend at Nhill.  Apparently, there are still some rooms and non-powered camping sites available.

 

The VicSouth Star Party is held just south of Nhill (Victoria, Australia) between the 9th and 12th of November.   Nhill is situated along the Dukes/Western Highways, near the border of South Australia and Victoria.  It is a very dark viewing site, perfect for viewing the night sky.  Achtung!:  Booking is essential.  Only camping sites are left.  Catering is now booked out.  It is still feasible to live, with the town of Nhill nearby.

 

Bring your own telescope.  Arrive before dark.  Public Night on Friday the 9th November.

 

BREAKING NEWS -- see Comet LONEOS (C/2007 F1) in the dark skies at VicSouth. This could become the third naked-eye comet for 2007.

LEONIDS METEOR SHOWER

Each year, the Earth passes through the dust and ice trail of comet 55P Tempel-Tuttle.  Even the smallest spec of dust, traveling at enormous speed, will light up in the sky to produce a shooting star (meteoroids).  The number of shooting stars vary from year to year depending on how much debris, and the path the Earth takes through it.  Some years have been particularly spectacular with ZHR Ratings (how many shooting stars are seen per hour) of well over 200!  Each year there are predictions of how good the Leonids shower will be, although these have proven to be highly inaccurate.  The only way to catch this spectacular display is to get out at the right time and have a look.  Here are some pointers:

 

- the Leonids Meteor Shower will be around between the 10th and 23rd of November with the best seeing generally in the middle of these dates (18th of November).

- no telescope or binoculars are needed, just your eyes.

- best equipment to have is a banana lounge (or similar).  This is so you don't get a crook neck looking up all the time.

- the later at night, the better.

- the shooting stars will appear from (radiant) the constellation of Leo (hence the name Leonids).

 

I have seen a high ZHR shower and is certainly something to remember!  8-)

INTRODUCTION TO WEBCAM ASTROPHOTOGRAPHY - ROBERT REEVES

In the last few years webcam astrophotography has exploded onto the astronomy scene. It has rapidly evolved from short exposure six-bit black-and-white imagery into long-exposure full-colour 16-bit per channel imagery of such quality that it rivals “conventional” means of astrophotography. Indeed, webcams have become the method of choice for planetary imaging.

$90AUD

 

 

INTRODUCTION TO DIGITAL ASTROPHOTOGRAPHY - ROBERT REEVES

This book is a 400+ page comprehensive, nuts-and-bolts introduction to digital astro-imaging written by Robert Reeves, an accomplished author and film imager with nearly 50 years of experience who has enthusiastically made the transition to digital imaging. Robert describes how the family digital camera you probably already own can be used to take spectacular pictures of the night sky. This is especially true if you have purchased a digital camera within the past several years - even some entry level point-and-shoot digital cameras take pictures of the Moon and planets that rival or exceed the best film images. If you already own a digital camera, telescope, and computer you probably only require a camera adapter and image processing software—some of which is free—to begin your night sky imaging adventures and unlike film you see your results almost instantly!

DOVETAIL PLATES FOR VARIOUS APPLICATIONS

The range of Dovetail Plates and mounting combinations has been increasing.  Here's an update:

 

Instead of Piggy Backing a Guide Scope or Camera on your main telescope, consider the advantages of placing the equipment side by side on a Heavy Duty DoveTail Plate.  Some of the main advantages of a Side By Side setup is more stability, easier to balance and also easier to work around.

 

Produced locally, the Side By Side setup is made up of a Heavy Duty DoveTail Plate to suit Celestron, Vixen, Skywatcher, Losmandy, Novosibirsk and other popular Mounts, and 2 separate detachable Side by Side Mounting Plates.  Plates are made from high grade aluminium and black anodised.

 

Detachable Side by Side Mounting Plates have an extra pre-drilled hole for mounting a Camera Bracket.  The Plates can also be fitted 90°.  This enables one scope to be fitted along the length of the Dovetail Plate, so the Dovetail Plate doesn't stick out.

 

Small Heavy Duty Dovetails to suit the Detachable Side by Side Mounts are also available.

 

345mm Heavy Duty Dovetail Plate $135

500mm Heavy Duty Dovetail Plate $165

Detachable Side by Side Mounts $90 each

Detachable Light Side by Side Mounts $50 each - 80mm Refractors and smaller.

 

Small Heavy Duty Dovetail Plates $75 each

Male to Male (standard to Losmandy) Dovetail Plate $120

 

All Plates and fittings allow popular mount sizes to fit each other, including the above mentioned brands.

 

 

LARGE ACHROMATS & APOCHROMATS IN CELLS NOW AVAILABLE

At long last it has finally happened.  We are now able to supply large achromatic and apochromatic lenses in their cells:

 

1200mm x 127mm - Achromat

$499AUD

 

990mm x 152mm - Achromat

$545AUD

SKYSHED POD OBSERVATORY UPDATE

Sorry for the delay about finalising the cost of the SkyPod Shed Observatories.  Organising the container costings takes a fair amount of time and effort, although it isn't much different to the other importing we do.

 

I will have the final costings by the end of next week.

 

I will also have information regarding New Zealand buyers.

 

There isn't any problem getting the Pods over here, just the logistics.

 

We still need to have at least 10 orders to fill a container.

 

I will have lots of Pod information ready for the VicSouth Star Party next weekend.  This will hopefully ensure at least one container full.

 

Payment will need to be upfront for this particular product.  A Pre Order 10% deposit will be needed with the full amount to be paid once the shipment is ready to set sail!  Usually 5-6 weeks at sea, then I pass them through customs etc.

 

I'll drop the Pods off myself, to the eastern states only, to help save shipping costs.  I expect the interstate shipping costs to be halved based on a quote from Toll/Ipec from Adelaide to Brisbane of $1100 for the Standard POD and $1300 for the XL-3 Pod.

 

The shipping from the US has worked out to be more expensive than first thought.  So if you have the price list I sent out a few months ago, disregard it.

 

www.skyshedpod.com

 

Let me know if you need any further information.  The SkyShed Pod website has all the information including sizes, forum and FAQs.

 

 

NEW R-G SOLAR FILM - 1000 OAKS OPTICAL

Designed with quality and cost in mind, our R-G solar film provides a superior image of the sun that rivals our glass solar filters at a lower price. Unlike other solar filter, the R-G solar film will provide a more pleasing and natural Yellow- Orange image of the sun our customers have come to know and love through our Solar Glass Filter product line. The R-G film will also be available in sheets for those who like to make their own solar filters. Please email us for Safety and other information, or see it here:

ASTRONOMY  CALENDAR  2008 - $12AUD

The Astronomy Calendar has the most stunning pictures.  It also has a lot of information and star maps for each month and in general.

 

 

ASTRONOMY  2008  BOOK  (18th  EDITION) $18AUD

Astronomy 2008 is an Australian publication suitable for whole of Australia.  It is intended for anyone who has looked up and wondered, whether it be with the unaided eye, binoculars or a telescope. It is intended to give a tourist's view of the sky as a 'use anytime' reference with realistic views identifying the positions of each object. It is also the easiest reference to use to find a planet's position in the night sky. The 2008 Edition contains extra pages on special events and deep sky objects.

TOUCAMS

 

NOW ABLE TO REPAIR TOUCAMS

We are now able to repair ToUcams by replacing the CCD Chip for $65 plus post.  This is the most common problem experienced with the cameras.  I haven't come across any other problems.

 

AMP OFF MODIFICATION

We are now able to do the "Amp Off" modification to the ToUcams for $40.  The Amp Off modification reduces the amount of glow from components used in the ToUcam.  This will cause a brightening on long exposures.

MIRROR MAKING GLASS

Currently we supply the following Glass types for mirror making - Soda Ash (Plate Glass), BK7, Pyrex and Suprax (Borosilicate).  The best material for mirror making is Zerodur.  Zerodur is produced by Schott.  It is a ceramic glass with an extremely low thermal expansion coefficient.  It has the following properties:

 

·  Nearly zero thermal expansion with outstanding 3D homogeneity

·  High internal quality

·  Good processing behaviour

·  Can be polished to a very high accuracy

·  Can be coated easily

·  Low Helium permeability

·  Non-porous

·  Good chemical stability

 

Well yes, it is expensive.  However, it is becoming available.  If you are interested in this type of glass for mirror making, let us know.

 

More information can be seen here:

http://www.schott.com/optics_devices/english/products/zerodur/

 

 

PYREX IS NO LONGER BEING MADE!

Dow Corning is no longer producing Pyrex.  If you wish to order a Pyrex 7740 Fine Annealed Blank, Tool, or Secondary Mirror, now is the time to do it.  I will allow 2 more days or so for final orders to come in.

 

Email us with your specs and we'll quote and add it to the order.

 

 

BOB'S KNOBS!

Bob's Knobs are popular the world over.  Bob makes a number of accessories to make life easier using a telescope.  Bob's Knobs prevent the use of tools for many telescope adjustments.

 

It’s easy... just grab a Bob's Knob and turn.  You can even do it while looking through the eyepiece on most scopes. And you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

 

Some of his most popular products include.:

 

Celestron Nexstar Telescopes;

Bob’s Knobs no-tools tripod bolts are available for the Celestron NexStar. These replace the factory Allen bolts so the telescope can be attached to the tripod without tools. They can also replace the factory plastic hand bolts that came with some NexStar 5 and NexStar 8 models. Our bolts are longer and have a larger knob, making installation and correct tightening much easier. The 5-point knobs are about 2.1 inches in diameter and have a non-slip surface for a secure grip. These will mount the Starizona Landing Pad without modification.

 

Meade Lightbridge 10” and 12” primary and secondary collimation knobs;

These replace factory screws so that collimation of both primary and secondary mirrors can take place without tools.  They also offer stronger primary mirror support springs for the Lightbridge 12" that will not sag like the factory springs.

 

Losmandy GM-8 and G-11 Mount no tools Tripod and Elevation Lock Knobs;

These replace factory Allen bolts so the mount can be set up and adjusted without tools.  The tripod bolts mount the GM-8 and G-11 equatorial head to the Losmandy tripod top piece.  The elevation lock bolts and washers secure the elevation adjustment on the GM-8 and G-11.  Bolts are stainless steel, and each has a plastic Tee handle that is 1-3/4" in diameter to provide adequate holding power when hand tightened.

ASTRONOMIK FILTERS

I promised a number of customers Astronomik Filters for which Astronomik in Germany were willing to supply.  The filters were to be around half the price of other retailers.  One of the retailers had a cry to Astronomik and now Astronomik will not supply to us.  I apologise to those people whom I promised these filters.  Hopefully Astronomik will change their minds in the future, and we can supply competitive pricing.  There has been some testing, and Astronomik certainly are very good quality items.  We have since gone with Baader Planetarium, which have an excellent reputation for fine filters and match any of the filters in the Astronomik range.

 

 

EXTRA TALL, STURDY BINOCULAR TRIPODS

We've been looking for a number of years, to find a very tall, sturdy tripod, which can take a large pair of binoculars for use in the night sky - which won't break the bank.  Now we've found them!  These tripods handle 20x80mm binoculars very easily.  Although 25x100mm (6kg) can be used on the tripod, we still recommend using a Manfrotto Tripod for Giant Binoculars over 5kg.

 

Tall, Sturdy Tripod $180AUD

Manfrotto Tripod $396AUD

Tripod to Binocular Adaptors $15

 

 

BLACKENING OUT YOUR BARLOW/EYEPIECE LENSES

A bit of research has gone into whether pulling your eyepieces apart, and blackening around the lenses sides, is effective for better viewing.  Well, it’s true!  Probably something you would rather do to a cheaper eyepiece or Barlow.  Just about all eyepieces can be unscrewed, carefully, and the lenses removed.  Please be aware, it is easy to mark lenses when putting them back together.  Don't use fingers, or the ends of pens or pencils.

 

 

BRIAN MAY FROM THE ROCK BAND QUEEN FINALLY DOES IT!

After more than 30 years as a member of one of the world's most successful bands, Queen guitarist Brian May has finally finished his PhD thesis he began as a student in the 1970s. May, 59, earned a degree in physics at Imperial College London but after years of studying interplanetary dust, he abandoned work towards his doctorate when Queen took off. His interest in the subject was reignited when he co-authored Bang! The Complete History of the Universe, which tells the story of the universe from the big bang through its subsequent evolution, and was released last year. "For the last nine months, I've done nothing except slave over my PhD, which is now written up, thank God," May said. May worked on the PhD between 1971 and 1974, and kept all his hand-written notes on the subject through the years, finally discovering them in his loft recently.

TOTAL ECLIPSE OF THE MOON 28TH AUGUST 2007

The Eclipse can be seen across Australia and New Zealand, although the greatest views will be in New Zealand and Eastern Australia.  Central Australia will get a good view, and Perth will only see the final stages.

 

EST

7.52pm - Total Eclipse begins

8:35pm - Full Eclipse

9.22pm - Total Eclipse ends

 

For observers in Adelaide (like me), head towards Broken Hill for the best view, away from city lights.

 

The Moon will appear a beautiful ruby colour.

 

Please note: next visible Total Eclipse of the Moon is in 2010!

 

 

ILLUMINATED RETICLES

The most popular use for the Reticle is Polar Alignment using the Drift Method.  Many people find this much easier, and more accurate than using a Polar Scope.

 

Illuminated reticles are also used for astrophotography guiding.

 

6mm Illuminated Reticle $95AUD

12.5mm Illuminated Reticle $95AUD

Rigel Systems Pulse Guide 12.5mm Illuminated Reticle $199AUD - Illuminator can be purchased separately for $70AUD

 

The Rigel Systems and Chinese Reticles have different patterns on them.  Let me know if you want an image of the reticle.

 

 

2009 ECLIPSE CRUISE

One of the most spectacular ways to see a Total Eclipse of the Sun is by ship.  Cruises are available for the 2008 Total Eclipse, which will be viewed from the Norwegian Sea.  In 2009, there is the Total Eclipse in the north western Pacific.  Information, including itinerary and reservations are avialable from Mayhugh Travel:

EXTRA WIDE FIELD EYEPIECE FOR ASTROPHOTOGRAPHY

I quite often get asked about the best eyepiece for wide field photography, which will not produce vignetting (narrow field of view) to make the most of the camera's film or capture area.  The William Optics DCL-52 Camera Adaptor Eyepiece ($144) produces ultra wide imaging with very little vignetting.  The focal length is 60mm and has field of view of 40°.  An Extension Tube ($68) may be needed for some scopes.  You can see the eyepiece here:

TURN YOU OLD 40MM PST INTO A 60mm/90mm/125mm PST! - by Phil Smith

Please note, this modification can only be done with the older PST.

 

 

The mod is about increasing the aperture on the PST from 40mm to 90mm or higher.  There are a few threads going on yahoo groups, most of the threads in the PST group have been deleted by the Group Moderator.  Also  http://ukastroimaging.co.uk (solar forum and project chat rooms), Google for " PST Modification Dodi" will show you at least one other users results of doing this, so far I found 9 people who have successfully modified their PST's to between 70 and 130mm aperture.  There is a lot more, not a lot of websites at this stage, but in the next few months I'm sure they will spring up.

The Mod involves a suitable F-Ratio scope, debate on this right now but a F5 to F7.5 Telescope to install the PST parts on seem to be favored but some are using F10, a Baader Cool ERF filter for UV/IR rejection, and the PST main body, or Etalon only, coupled with either the integrated BF5 on the PST (the blocking filter at the EP end) or a replacement BF10 if you want to use a longer focal length scope.  The web site listed below is a set up where the guy swapped his 40mm Ha set up to a 67mm HA setup with this mod.  Im still trying to get the full details complete clear for safety reasons.

 Arthur Edwards
http://www.ambermile.co.uk/ is making machined tube adapters for this mod, last I heard for £30 it is not on his web site yet so you have to email him at info@ambermile.co.uk

EYE ON THE SKY - BOOK BY GEOFF ANDERSEN

Eye on the Sky is all about optical telescopes - their history, operation, discoveries, development and future. Telescopes and their use in astronomy and surveillance are increasingly fascinating to people, yet few know much about them. This superb book provides easy-to-understand factual information, as well as an exciting glimpse into the future. It offers a clear explanation of how telescopes work and why the costs for building them can aptly be described as astronomical. In addition to the telescope’s role in conventional astronomy, Dr Andersen describes telescopes used during the day (solar observatories), for detecting ripples in the fabric of space-time (gravitational wave detectors) and even for gathering extra-galactic particles (neutrino and gamma-ray observatories). As well as this, it looks at other uses for telescopes such as lidar, optical communications and space surveillance. The latter is something of great interest to the average reader, and it will answer the most common question: Just what can spy satellites see from space?

HOW TO SHARPEN YOUR CCD IMAGES

Sharpening is an important part of digital image processing. It restores some of the sharpness lost in the lens and image sensor. Virtually every digitized image needs to be sharpened at some point in its workflow- in the camera, the RAW conversion software, and/or the image editor.

 

The following web site delves deeper into sharper digital images.

STELLACAM II SPECIAL- $995AUD

The StellaCam II is an excellent introduction to Deep Sky imaging for those who appreciate the versatility of a "True" video camera. The output of the camera can be displayed on a TV, VCR, Monitor, Laptop or desktop computer.

The On-Screen (Monitor) image of brighter objects Messier objects such as the Dumbell Nebula rivals processed CCD images. The views on the monitor are spectacular. This improvement makes the StellaCam II especially well suited for school, planetariums, college, universities and industry and both the beginning imager and advanced imager.

There is a separate remote control box for slow shutter speed (frame accumulation), gain, gamma (contrast) control and freeze frame.

The freeze frame button will freeze your on screen image on the monitor. This is useful when you have an image you want to describe or display for a large group. Once the screen image is frozen, the telescope can be slewed to the next object while a discussion is being a given for the current on-screen image.

See the excellent review of the StellaCam II in the October 2004 Issue of Sky & Telescope Magazine

Following are two quotes from the review:

"AVA's latest offering for deep-sky video work is the StellaCam II. ... , but it can stack twice as many frames allowing it to probe deep into the night sky. ... it not only produces a deeper image but also delivers one with far better tonal quality and less electronic noise." - Johnny Horn, Sky and Telescope

"Although, StellaCam II is more expensive than its predecessor, .... it offers extremely compelling views of deep sky objects. In some cases it even produced images comparable to those shot with low-cost astronomical CCD cameras, but without the fuss of image calibration." - Johnny Horn, Sky and Telescope

Astrovid - StellaCam II B&W CCD Video Integrating Imaging System, Hand Camera Control Unit, 1.25"-C Adapter, 25' Shielded Video Cable, 12VDC Power Supply And One Year Warranty.

 

 

STELLACAM EX SPECIAL - $810AUD

The StellaCam Ex uses the most sensitive 1/2 inch format CCD available, the SONY 600 line EXView CCD. This camera is 2X more sensitive than non-EX-View CCDs in the visual range and 4X more sensitive in the near infrared. (800-900 nm). This camera can also be run up to 100 feet away from the telescope with optional extension cables.

INTRODUCTION TO WEBCAM ASTROPHOTOGRAPHY - ROBERT REEVES

In the last few years webcam astrophotography has exploded onto the astronomy scene. It has rapidly evolved from short exposure six-bit black-and-white imagery into long-exposure full-colour 16-bit per channel imagery of such quality that it rivals “conventional” means of astrophotography. Indeed, webcams have become the method of choice for planetary imaging.

INTRODUCTION TO DIGITAL ASTROPHOTOGRAPHY - ROBERT REEVES

This book is a 400+ page comprehensive, nuts-and-bolts introduction to digital astro-imaging written by Robert Reeves, an accomplished author and film imager with nearly 50 years of experience who has enthusiastically made the transition to digital imaging. Robert describes how the family digital camera you probably already own can be used to take spectacular pictures of the night sky. This is especially true if you have purchased a digital camera within the past several years - even some entry level point-and-shoot digital cameras take pictures of the Moon and planets that rival or exceed the best film images. If you already own a digital camera, telescope, and computer you probably only require a camera adapter and image processing software-some of which is free-to begin your night sky imaging adventures and unlike film you see your results almost instantly!

http://www.siebertoptics.com/SiebertOptics-Ortho%20page).html

 

Here's some comments from Cloudy Nights Review Site:

 

Nobody has yet mentioned what might be a very significant planetary EP line. The Siebert Optics Orthoscopic/Star Splitter Series looks interesting. 65* AFOV, 10mm eye relief in all FL's, 13 FL's from 2.9mm to 9.9mm. Guaranteed to outperform anything you have or your money back. At $79 to $129 each, they aren't cheap, but the money back guarantee has me interested. They seem to be a Barlowed design like the Radian, hence the common 10mm eye relief throughout the line, and the rather long physical dimension. The Radian and TMB are a little too fat for my taste, and 10mm eye relief is plenty for me. I can't lose by trying, and since I have 7.5mm and 10mm Ultimas to test them against, not to mention my 9mm TMB's, they are in for a very tough test if I decide to give a pair a try. These are not cheap EP's, and nobody can accuse Siebert of being good "for the price" with these, as they cost more than much of their competition, although with bigger oculars and longer eye relief. I have a feeling they just have to perform to pull people away from the old classic planetary designs, much as the Burgess TMB EP's have done. The Star Splitter eye relief will be much longer at a standard 50* AFOV, so they will have no real disadvantage against the TMB/Radian if they are razor sharp to the edge. And check out all those 13 different FL's!!! You can get EXACTLY the FL's you need and not have to settle for a 6mm or 9mm if you need a 7.5mm. Yep, when I get some more EP money to feed the addiction...............

ORTHOSCOPIC EYEPIECES FOR THE PLANETS

Orthoscopic eyepieces are amongst the best eyepieces to use on the planets, or for high magnification.  A number of manufacturers stopped making the Orthoscopics, possibly due to the revolution of wide field eyepieces now available, and the popularity of the Plossl eyepiece.

 

Harry Siebert has brought out a new range of Orthoscopic eyepieces.  They have an enhanced 5 element design.  The Clear Aperture (hole you look through) is a generous 13mm diameter.  The wide range of Focal Lengths allows a telescope owner to get the exact highest magnification required.  The eyepieces have a 60°+ Field of View.:

 

2.9mm, 3.4mm $195AUD Best suited to F/4 to F/15 Focal Ratio Telescopes.

3.9mm, 4.4mm, 4.9mm, 5.4mm, 5.9mm, 6.4mm, 6.9mm, 7.4mm, 7.9mm $150AUD - Best suited F/4 to F/15 Focal Ratio Telescopes.

8.9mm, 9.9mm $120AUD - Best suited to F/6 and over Focal Ratio Telescopes.

10" FORMATUBES BACK IN STOCK

A number of people have been after Tubes to suit 10" telescopes.  These are back in stock now.

 

 

BOB'S KNOBS!

Bob's Knobs are popular the world over.  Bob makes a number of accessories to make life easier using a telescope.  Bob's Knobs negate the use of tools for many telescope adjustments.

 

It’s easy... just grab a Bob's Knob and turn.  You can even do it while looking through the eyepiece on most scopes. And you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

 

Some of his most popular products include:

 

Celestron Nexstar Telescopes;

Bob’s Knobs no-tools tripod bolts are available for the Celestron NexStar. These replace the factory Allen bolts so the telescope can be attached to the tripod without tools. They can also replace the factory plastic hand bolts that came with some NexStar 5 and NexStar 8 models. Our bolts are longer and have a larger knob, making installation and correct tightening much easier. The 5-point knobs are about 2.1 inches in diameter and have a non-slip surface for a secure grip. These will mount the Starizona Landing Pad without modification.

 

Meade Lightbridge 10” and 12” primary and secondary collimation knobs;

These replace factory screws so that collimation of both primary and secondary mirrors can take place without tools.  They also offer stronger primary mirror support springs for the Lightbridge 12" that will not sag like the factory springs.

 

Losmandy GM-8 and G-11 Mount no tools Tripod and Elevation Lock Knobs;

These replace factory Allen bolts so the mount can be set up and adjusted without tools.  The tripod bolts mount the GM-8 and G-11 equatorial head to the Losmandy tripod top piece.  The elevation lock bolts and washers secure the elevation adjustment on the GM-8 and G-11.  Bolts are stainless steel, and each has a plastic Tee handle that is 1-3/4" in diameter to provide adequate holding power when hand tightened.

 

Please inquire for pricing.

NEW HEAVY DUTY DOVETAIL FOR SIDE BY SIDE SETUP - UPDATE

We have now introduced a longer 500mm Heavy Duty Dovetail Plate allowing larger telescopes to be placed side by side.

 

Instead of Piggy Backing a Guide Scope or Camera on your main telescope, consider the advantages of placing the equipment side by side on a Heavy Duty DoveTail Plate.  Some of the main advantages of a Side By Side setup is more stability, easier to balance and also easier to work around.

 

Produced locally, the Side By Side setup is made up of a Heavy Duty DoveTail Plate to suit Celestron, Vixen, Skywatcher, Losmandy and other popular Mounts, and 2 separate detachable Side by Side Mounting Plates.

 

Detachable Side by Side Mounting Plates have an extra pre-drilled hole for mounting a Camera Bracket.  The Plates can also be fitted 90°.  This enables one scope to be fitted along the length of the Dovetail Plate, so the Dovetail Plate doesn't stick out, if only one telescope is used.

 

Small Heavy Duty Dovetails to suit the Detachable Side by Side Mounts are also available.

 

345mm Heavy Duty Dovetail Plate $135AUD

500mm Heavy Duty Dovetail Plate $165AUD

Detachable Side by Side Mounts $90AUD each

Small Heavy Duty Dovetail Plates $75AUD each

 

 

AN IDEAL ASTROPHOTOGRAPHY SETUP

The most popular setup being used for astrophotography at the moment is the Side by Side Dovetail Plate outlined above.  Mounted upon this system is a main telescope for imaging eg. Celestron SCT, Russian Maksutov (Klevstov), or Newtonian Reflector.  A smaller Guide Scope is setup beside the larger imaging telescope eg. 60, 70, or 80mm ED Refractor.  The Guide Scope utilises a ToUcam modified for Long Exposure.  The camera keeps a star centered using software.  The Guide Telescope can be placed in Guide Rings.  These are similar to your Finderscope.  The Guide Telescope can be adjusted to point at the exactly same spot as the imaging telescope.

 

 

PHILIPS TOUCAM 840K $145AUD

PHILIPS TOUCAM 840K MODIFIED FOR LONG EXPOSURE $285AUD

Basically, there is one setup for the planets and Moon, and another setup for deep sky objects.  If the ToUcam has the Long Exposure Modification, then both can be done.  A physical switch allows the change between Video and Long Exposure.

 

Firstly, it is best to use Focal Projection (no lenses used between the ToUcam CCD and the telescope ie. 1.25" ToUcam Adaptor) for the planets and Moon.  A Barlow is used for extra magnification.

 

Secondly, a low, wide field magnification is best suited for deep sky objects.  This is where the 40mm Plossl 1.25" Adaptor ($130AUD) is used.  With this setup, an eyepiece is used between the ToUcam CCD chip and the telescope and is called Eyepiece Projection.

 

There are other ways to achieve different magnification, although the information above pretty covers it.  The other ways include:

 

- Eyepiece Projection Adaptor ($45AUD) which allows different Focal Length eyepieces to be used.  This is done by placing the desired eyepiece inside the Eyepiece Projection Adaptor.  A ToUcam T Ring Adaptor ($45AUD) is needed for this.  This adaptor screws into the ToUcam.  It has a T Thread on the other end which screws into the EPA.

 

- Focal Reducers ($95AUD) are available for both camera/camcorder setups.  The
whole idea of deep sky photography is to get a wide field of view, brighter
objects through lower magnification.  This reduces exposure time making
tracking easier and more accurate.  Focal Reducers turn an F/10 into an
F/6.  There is also an Extender ($30AUD) which extends the F Ratio further to
F/4.

 

Baader IR/UV Filters ($80) produce a clearer image when used on bright objects like the planets and Moon.  CCD chips received too much IR (infra red), and so these filters cut it down.  If your telescope is a short focal ratio achromat refractor, then the filter can also be used to cut down the coloured blooming (UV - Ultra Violet) which is inherent with short focal ratio achromats, when used on planets and other bright objects.

 

If I have confused the hell out of you, please give me a ring and I'll explain it all.

WILLIAM OPTICS DEALER & PRICELIST

The full William Optics range is available.  Apparently we're the cheapest!?  Here's our price list.:

http://www.telescopes-astronomy.com.au/william_optics_telescope_usa_astronomy.htm

 

 

DOBSONIAN  TRACKING  PLATFORMS

We are hard at work developing a Dobsonian Platform for Tracking.  The Platform will enable the user to keep an object centered for around 45mins.  This is particularly useful for long stares at planetary and Moon details, and of course, any other object.  Although the Platform is not intended for astrophotography, there will be an improvement over other methods of taking images using a Dobsonian telescope (Astrophotography with a Dobsonian article - October 2005).  We estimate the pricing to be around $400 to $500 for an 200mm or 250mm Dobsonian.

 

Let us know if you are interested and what sort of Dobsonian you have, and the size.

 

 

TELESCOPE SECONDARY SPIDER DEFRACTION ARTICLE

When viewing through a telescope with a Secondary Spider, the shape affects the Diffraction Patterns seen around an observed star.  A 4 Vane Spider will produce 4 spikes around a star.  A 3 Vane Spider causes 6 spikes around a star!  This is unwanted by some astrophotographers who would prefer to have no spikes showing in their photos.  One way to achieve this is, and also reduce obstruction, is to use curved types of Spiders or similar.  The following article gives a lot of information about Spiders and diffraction.:

http://imaging.creol.ucf.edu/publications/Spider_Diffraction.pdf

 

 

QUANTUM THEORY OF GRAVITY - UPDATE

Here is an interesting update for combining the Theory of Gravity, Mathematics and Quantum Theory to produce an overall theory of every thing.:

12", 13.1" or 14" DOBSONIANS - READY FOR OPTICS & FOCUSER

The 12" to 14" Ready Made Dobsonian Telescopes can be tailored to your budget and performance needs.  Construction from Laminated Wood and Sonoco Cardboard Tube, the telescopes have been constructed by Ron Royle (formerly of the Sydney Observatory), one of the most well known telescope makers in Australia.  This has resulted in a very sturdy design in construction and smooth movement.  The telescopes have been available to the Australian public for a number of years.

 

A large number of variable components can be used with the telescope.  Firslty, there is a choice of Mirror size, focal ratio, accuracy and material.  Secondly, a variety of Focusers from a Standard Rack and Pinion 32mm to a Ultra Low Profile Crayford 50mm.  Thirdly, there is a choice of Finderscopes.  Encoders and Equatorial Platform are also an optional extra.

 

The Telescopes are $660 plus shipping.

EVER WONDERED HOW?

Have you ever wondered how its possible to get those fantastic shots of the planets through your standard Cassegrain Telescope?  The Lymax "Cat Cooler" is used to ventilate the inside of a Cassegrain telescope, allowing a faster equilibrium, resulting in better images, faster!  The enclosed design of Cassegrain telescopes allows warm air and current to stay inside the Optical Tube for many hours.  Venting can only be achieved using the small hole where the diagonal goes.  Air which goes into the Optical Tube Assembly is filtered.

PLOP FOR MAIN MIRROR CELL DESIGN

One of the most popular programs available free on the internet for telescope builders is PLOP.  PLOP, which is a CAD tool, allows the builder to enter all his variable details into the program which will calculate the design of Mirror Cell best suited to the mirror.  Variables include Mirror material, focal ratio and thickness.  Wave front error can be optimized as much as 50%.  Optimization also means a larger mirror can be supported which normally cannot.

USING 2" EYEPIECES ON MEADE ETX TELESCOPES

Harry Siebert has designed an Eyepiece Adaptor for using 2" Eyepieces on ETX Telescopes.

 

Is it advisable to use 2" eyepieces on a Meade ETX scopes?  Is there a benefit?  ETX's have a relatively long focal distance for a small scope and with 1.25" eyepieces cover a relatively small section of the sky.   With the right 2" eyepiece you can at least double the amount of sky you can see.  Sometimes it can come close to triple.  Is this a gain?  The extra apparent field is there, but can't be seen in a 1.25" eyepiece.  A standard 32mm Plossl has a maximum apparent field of 52 degs.  With the Siebert 32mm Ultra Plus with a 70 deg. apparent field is almost double at 1.8x the amount of sky.   With the Siebert 36mm observatory class eyepiece this goes to 75 degs. apparent field, this goes to almost 2.5x the amount of sky.   So this represents a tremendous gain and if you think about it, doubles.   The amount of light you are seeing because you are seeing more of the sky.  This adapter comes with full instructions and is easy to install. The adapter slides over the 1.25" eyepiece socket which increases the internal size because no 1.25" barrel is inserted.  This means that an incredibly low power, wide angle lens can be used with zero vignetting.  Can you image a 40mm with 70 deg. apparent field in your ETX?  Many may have thought that this was impossible, but with this adapter it works perfect and can slew to the zenith with no problem.

NEW GEARS FOR EQ6 MOUNTS

For years, many of the Chinese telescope Mounts have been improved simply by pulling them apart, cleaning up the gears and replacing the grease.  A higher end solution is to replace the worm gear and shaft.  The EQ6 Mount has been notorious for having problems caused by its bad worm gear and shaft.  This is caused by the two components being made from two different materials (brass and steel).  These components can be replaced by high quality gear and shaft.  The replacement components are made from high quality material and reduce Periodic Error by 50% - 70%.  Please contact us for more information and pricing.

PLUTO OCCULTS STAR

On the 12th of June, Pluto's system occulted star UCAC 2603 9859 which is 15th magnitude (brightness scale).  Predictions had the main line of visibility at latitude of around 45° south.  As it turned out, the line of visibility occurred further north at around 36°.  A number of teams were sent out from the USA to capture this event as it gives valuable information to astronomers about Pluto including:


- atmospheric static conditions (Temperature, Pressure etc.) and to compare it with data from past occultation’s, to get an idea of the development of Pluto's atmosphere during the loss of energy due to the increasing distance from the sun.
- to determine winds in Pluto's atmosphere by a possible measurement of a central flash from Tasmania or New Zealand.
- to determine a possible ring system around Pluto

 

Valuable information about Pluto's newly discovered extra moon (P2) also needed collecting:


- to determine the diameter of P2
- to determine the mean density of P2

One team was sent to Adelaide where they used a borrowed 30" diameter reflector from one of our local Astronomical Society members.  The team was equipped with lots of mega buck equipment for capturing the event.  Meanwhile, a couple of intrepid Astronomical Society of South Australia members, decided to have a go themselves using the society's 20" Reflector and a Meade LPI Camera.  Obtaining the images was particularly difficult as the full Moon was right next to Pluto!  After much preparation, and a failed laptop keyboard resulting in a dash back to town, 2 hrs drive away, several images were captured and results examined.  Initial results from the 20" Reflector and Meade LPI showed an atmosphere around Pluto!  This showed how easily contributions to space science can be made with simple equipment.  Although the telescope was quite large, it was not necessary.

 

Another occultation is currently occurring, and the boys are out there again to see what other information they can find out about the solar system.  This shows just how ordinary telescope owners can contribute information.

USE OF GREEN LASERS ON STREET LIGHTS

Everyone knows what nuisance street lights can be to amateur astronomers observing the night sky.  A number of people have been using their Green Laser Pointers to activate the sensor on some street lights to switch them off.  We do not condone this practise.

 

 

GUIDING EYEPIECE ILLUMINATOR WITH 12.5MM PLOSSL

Rigel Systems produces only a small number of products.  Each product has been carefully designed to be highly useful.  One of its most popular products is the PulsGuide + Illuminated 12.5mm Plossl Eyepiece.

 

PulsGuide pulses the reticle illumination to let the eye rest between pulses. The result? Improved contrast between reticle and faint guide stars for easier guiding and better astrophotography or acquisition of faint object in your finderscope.

 

Two Knob Timing Control and Adjustable Brightness -- 2 knobs let you independently tailor on and off blink times from continuous on to long-on/short-off or short-on/long-off or anything in between.

 

Two Color LEDs -- Comes with red LED which you can switch to yellow LED by unplugging red and plugging in yellow. Some astrophotographers find low level yellow makes the cross hair clearer and sharper, and makes guiding even easier.

 

Available With or Without Eyepiece -- Use our quality, dual crosshair, 12.5mm Plossl eyepiece or with your eyepiece or finder. Fits standard 8mm threaded hole. 10mm and 14mm set screw adapters available. Uses one long life lithium battery (included) that is available at most electronics, camera and hardware stores.

"Some observers therefore prefer a cross hair that flashes on and off while guiding. For this reason, Rigel Systems designed a guiding light source called "Pulsguide", a simple but effective invention that pulses the reticle illumination of a guiding eyepiece during an exposure. On and off times and the reticle brightness are all variable and the unit is compatible with many existing guiding eyepieces. For guiding on very faint guide stars, I find this gadget invaluable."
Martin Mobberley in Astronomical Equipment for Amateurs.

 

"PulsGuide solves the problem of how to guide on faint stars while keeping the crosshairs bright. I use mine constantly. I prefer a yellow reticle illuminator because I'm sure my eye is focusing it in the same plane as the star." Michael Covington, author of Astrophotography for the Amateur.

"...indeed with PulsGuide I was able to track stars that were virtually at the limit of what I could see in the eyepiece when no reticle illumination was present."
Dennis di Cicco in Sky and Telescope

"...fainter stars may be spotted and followed with greater ease...".
Phillip S. Harrington in Star Ware

GALAXIES  CLUMP  FROM  DARK  MATTER

Very interesting article from the Subaru Telescope Team.  A clump of over a million galaxies can be seen in the constellation of Cetus around 8 billion light years away.  The formation process and evolution of galaxies contributes to the understanding of Universe.  Galaxies are located at different distances, hence we see them at various stages of their lives.  Data obtained is of a very high value, especially once the complimentary data made up from different wave lengths is added in the near future.:

BAADER  TURBO  FILM  -  PROTECT  YOUR  OPTICS!
This is the essence of AstroSolar ™ safety film. A highest precision, crystal clear material (not "Mylar"). It is a monomer film which we found after thoroughly testing more than 200 different film samples on our Zeiss autocollimator. This film was used in german Science Institutes as optical membrane for nuclear and particle physics experiments. The basic substrate has been further refined and homogenized by a proprietary annealing process that was developed exclusively for us. Due to these treatments Turbo Film attains perfect homogeneity and performs equal to a 1/10 wave plane parallel optical window. In fact it has the lowest wedge error of any existing optical window. TurboFilm will protect your valuable optical equipment, close telescope tubes against dust and humidity, greatly reduce air currents - all without reducing the optical quality of your telescope.

 

 

EDMUND  SCIENTIFC  RKE  EYEPIECES

I have been using Edmund Scientific RKE Eyepieces for a very long time.  The eyepieces are designed as a reverse Kellner.  They are very good eyepieces and have been kind of hard to get hold of.  Finally, people are finding out how good they are, with reviews starting to appear on the net.  I use these eyepieces for public viewing sessions.  In particular, the 28mm RKE always gets a WOW! and until now, I have not been able to supply these eyepieces to the many people who want to know where they can get them from.

10th PLANET OF SOLAR SYSTEM

In October 2003 scientist's discovered a bright object, the small icy world is the most distant solar system body ever discovered. The discovery came about when a team at the California Institute of Technology lead by Dr. Micheal Brown, had been following the object, which, for over a year, gradually built up enough data to compute an orbit and verify the object's nature. The object is a typical member of the Kuiper Belt, but it's sheer size in relation to the nine known planets means that it may be classified as a planet, yet that claim is already being contested which could open a healthy debate as to what really constitutes a planet. The new object — as yet unnamed, but temporarily known as 2003 UB313 — is now 9 billion miles away from the sun, or 97 times as far away as the Earth and about three times Pluto's current distance from the sun. Its 557-year elliptical orbit brings it as close as 3.3 billion miles. Pluto's orbit ranges between 2.7 billion and 4.6 billion miles.

Astronomers do not have an exact size for the new planet, but its brightness and distance tell them that it is larger than Pluto, the smallest of the nine known planets.

"It is guaranteed bigger than Pluto," said Michael Brown. "Even if it were 100 percent reflective, it would be larger than Pluto. It can't be more than 100 percent reflective."

The name planet means wandering star. For thousands of years, people have noticed planets moving through the apparent, unmoving stars of the constellations. We now know the close proximity of the planets make them appear as moving quickly through sky compared to the background stars.

As astrology is based on the positions of the planets, the finding of the 10th planet has made all previous astrological predictions inaccurate. Not only has the 10th planet given cause for debate over astrology, it has also caused debate to what really defines a planet. Pluto is smaller than our Moon, although it is classified as a planet! Does the location of Pluto and the new 10th Planet make them Kuiper Belt objects - the comet and asteroid type objects which surround our solar system? The term planet is so old, that is not a scientific description. Dr. Michael Brown, leader of the 10th planet discovery team, says the term planet is simply not a scientific word, it is a cultural word.

AUTOCOLLIMATORS

I tend to go on about these a fair bit.  Owning a 16" F/4.5 Reflector, I find them invaluable.  Accuracy on a short focal ratio telescope is crucial.

 

To Understand how the autocollimator is used, consider the following analogy:

 

A fun house has two mirrors facing each other in a room.  One of the mirrors can be moved by using a lever in the center of the room.  If you stand in the center of the room and look in one mirror, you will see your reflection.  If the two mirrors are not exactly parallel, you will also see a reflection of your reflection in the other mirror.  These reflections will go on for what seems forever, creating a line of ever smaller images of yourself.  When the mirrors are parallel, you will only see your reflection in the mirror because your body is blocking the reflection from the other mirror.  Suppose another person is looking through a small hole in the fixed mirror.  This hole is centered on the position where you are standing.  When the mirros are slightly out of parallel, he sees you and a series of reflections of you in the mirror behind you from his perspective.  When both mirrors are parallel, he sees only you and no reflections.

 

If a flat mirror is placed in the focuser of a Newtonian telescope and it has a small hole placed in it to look through, the center of the primary along with secondary and the mirror in the autocollimator act like the two mirrors in the example.  When a Newtonian is properly collimated, all the multiple reflections will appear as one.

 

A standard collimator or laser is used first to get the rough alignment.

AutoCollimator $95AUD$

DEEP  IMPACT - THE  FIRST  LOOK  INSIDE  A  COMET

For six years NASA has been developing a spacecraft, which left earths orbit on January 12th 2005, and is headed straight towards Comet 9P/Tempel 1. Deep Impact’s Spacecraft will release a probe which will collide with the comet on July 4th 2005.

 

NASA has been working on the development of the spacecraft which has been designed to collect information about the comets surface and also reveal the secrets of the interior of the comet. The impactor is a battery powered spacecraft that operates independently of the flyby spacecraft for just one day, after its release, it will take over its own navigation and maneuver into the path of the comet. A camera attached to the impacter will capture and relays images of the comets nucleus until just seconds before impact.

 

The impactor spacecraft is constructed mainly of copper (49%) and weighs 370kg. The impactor contains the copper impact body, scientific instruments, guidance computer, solid rocket attitude control thrusters and communications gear. It will plough through the comet's thin crust and on into the interior where the heat of friction between the impactor and the comet will cause it all to vaporize. A tremendous explosion will occur. A crater is expected to form upon impact creating a bowl shaped crater as wide as a football and approximately 15 stories deep.

 

The effects of the collision with the comet will also be observable from certain locations on Earth and in some cases with smaller telescopes.  The data is analyzed and combined with that from other missions, from telescopes around the world, and in Earth orbit. These results will lead to a better understanding of both the solar system's formation and implications of comets colliding with Earth.

 

Some doubts have be raised to how well this event will be seen through a telescope or binoculars. Some believe the probe will miss altogether!

 

Tempel 1 will be able to seen at around magnitude 9 before the impact. This means the comet can be seen by a small telescope or binoculars in areas of low light pollution. If all goes well, once the probe has collided with the comet, estimates say the comet will brighten to around magnitude 6 or better.  Best views will be from New Zealand where it will be near overhead.

 

The expected viewing time for the impact in Australia is between 5:50am and 6:00am Universal Time, which unfortunately for viewers in Australia, is not visible due to it still being daylight.  Once dark, the result of the impact will be seen through telescopes or binoculars.  NASA is broadcasting the mission via the internet live (google search "NASA TV").

 

Here are some links regarding information about the mission:

http://deepimpact.jpl.nasa.gov/

 

http://www.space.com/deepimpact/

 

A competition is being run by The Planetary Society to guess how big the crater will be made by the probe. For competition details visit:

http://www.planetary.org/deepimpact/contest_enter.html

 

There are a lot of opinions about this mission, with some people saying there may be a Butterfly Effect.  One woman is suing NASA for disturbing the harmony of the solar system!

SETI @ HOME  - The search for extraterrestrial life at home

Seti at Home allows anyone to use their home or business computer to analyse data received from the Aricebo Observatory.:

http://www.answers.com/topic/arecibo-observatory

 

By downloading a small and simple program from Seti @ Home, PC owners can receive units of data, analyse them, and send back to Seti.  Each unit of data can take up to 24 hours to analyse depending on the speed of your computer.  The program runs as a screensaver which means it only runs when the screensaver comes into effect and doesn't interupt any other programs.

 

As units are completed and sent back, certificates are issued for certain milestones eg. 50, 100, 500 units etc.  Anyone who produces a result will receive the credit for finding it.  There are currently 5.5 million users and the number grows by about 300 a day.  Seti's Home page is here:

http://seticlassic.ssl.berkeley.edu/index.html

 

To download the Seti at Home program Screen Saver Version click below or there are Command Line Versions, see below.

http://seticlassic.ssl.berkeley.edu/download.html

 

There are also command line versions which doesn't have the pretty screensaver graphics, although, unit analysing speed is greatly increased.  Some command line versions produce lots of information about your computer and the analysing process.  To see different versions of the Seti at Home programs, visit here:

http://www.seti.nl/content.php?c=downloadwin9x&language=1

 

To use the one we use, go the the page above and download "Easy CLI Setup".

 

There are clubs and groups.  Telescopes and Astronomy have just started a group and anyone is welcome to join.  To join our group, please visit the following page:

http://setiathome2.ssl.berkeley.edu/stats/team/team_193848.html

 

Two new programs includes Einstein @ Home and Climate Prediction.  Einstein @ Home uses your computer's idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO and GEO gravitational wave detectors.   One of the most accurate ways of testing Einstein's Theory of Relitivity is using neutron stars being the most accurate time clocks in the universe.

 

Climate Prediction is the largest experiment to try and produce a forecast of the climate in the 21st century.  Once again it uses the idle time on your computer.

PLANET  CONJUNCTION  BETWEEN  SATURN,  VENUS  &  MERCURY

Starting on the 24th of June, a conjunction between Saturn, Venus and Mercury will occur.  A conjunction is an approximate lining up of a number of celestrial objects.  All 3 planets will start off being just under 4 degrees of each other on the 24th of June.  They will continue to dance close to each other for the next 3 days.  On the 25th of June the planets will be within 2.2 degrees of each other.  On the 26th June at around 5.00 UT (Universal Time) the planets will separated by only 1.5 degrees.  The planets will stay within 2 degrees of each other on the 27th.

 

Conjunctions of this type make good specimens for videoing through a telescope.  It is not necessary to wait for darkness to image the planets.  The major planets can be seen through even small telescopes during the day.  This may be difficult as there is no reference to finding your objects, unless you have a goto!  Caution must be taken not to point your telescope at the Sun unless the appropriate filters or setup is used.

 

To convert UT (Universal Time) to your time, see the article earlier in the Newsletter.

 

 

SOCIETY  MEMBERS  GET  THERE  BENEFITS - Hire Telescopes

A number of Astronomical Societies and Clubs have Telescopes for hire.  These are generally fairly large in Aperture and generally of the Dobsonian type.  To hire these telescopes is very inexpensive.  Our society (Astronomical Society of South Australia) have a 8" Dobsonian for $20 per month and $20 refundable deposit.  We're not the only ones.  Check your local society or club.

 

 

PENTAX  BINOCULARS  ON  SPECIAL

ANTI  VIBRATION  SUPPRESSION  MATERIAL

These really work.  Cut down how long it takes for the telescope to stop shaking.  Helps greatly in preventing outside movement from shaking your telescope.  Don't bother paying $100AUD when we have the material for $45AUD or $35US or £18

 

 

REFIGURING  YOUR  MIRROR

We currently have 3 experienced mirror makers who are able to refigure your current mirror.  If you have a Chinese made mirror which isn't up to scratch (yes, that's all of them), we are able to hand correct the optics and re-aluminise the surface with high quality coatings.  We have found the majority of mirrors have been overcorrected, have bumpy surfaces and errors, made by machine polishing.  If you want to know the difference it makes, pop along to an Astronomical Society viewing night, and have a look through a telescope who's mirror is hand made.

 

Let us know the size and focal ratio of your mirror, and we'll quote its facelift.

2  OF  JUPITERS  MOONS  TRANSIT  ON  24TH  JUNE

2 of Jupiters moons will move across its face on June 24th.  You will need a telescope of the bare minium of 114mm Reflector or 70mm Refractor, and favourable seeing conditions.  The shadows of Io and Europa will move at different speeds starting with Io entering the scene (ingress) at around 7.15 UT.  Europa's shadow will ingress at 8.30 UT.  Io's shadow will dissappear (egress) around 9.30 UT and Europa's shadow will egress at around 11.15 UT.  To convert UT (Universal Time) to your time, see the article earlier in the Newsletter.

 

 

PLANETARY  ATMOSPHERIC  DISPERSION  CORRECTOR  THINGY

The PADC - 1.25" Prism Assembly, with 4° (or 2°) 1/10th wave AR coated prism, 1.25" Eyepiece Holder has received some good reviews.  "What does it do?":

 

- For Visual & Imaging.

- will realign the Red and Blue wavelengths of objects 40 degrees and lower in the sky. 
- will work for all telescope types.

JUPITER  -  MOON  OCCULATION

 

General World Information:

On February 27th, an occultation will be visable between the Moon and Jupiter.  The observer will see the planet Jupiter very close to the Moon, or being occultated (the blocking of the light by a nearer object, usually by a solar system object).

 

Telescope owners will be able to see both Jupiter and the Moon, together, in the field of view.  This makes an excellent and interesting photograph or image.

 

The occultation will be observed from the following places:

 

Australia, New Zealand, Africa, South America, Alaska, Eastern Siberia and Antarctica.  Check the following web site for location times:

 

http://www.lunar-occultations.com/iota/planets/planets.htm

 

Australian Information:

The 2 Celestial bodies will graze each other for observers, along an arc, between Melbourne and central Western Australia.

 

Perth observers will see Jupiter reappear 20mins after the Moon rises.

 

For further information including times, use the following keywords in your search engine:

NIGHTSKY  CEILINGS

Click on the link below to see how your bedroom, lounge, or any room at all will look with Constellations, Planets, stars, comets and shooting stars painted on as a mural.  One of the best effects I've found, is a Globular Cluster.  Its invisable by day, and incredible by night!  Make your room into a planetarium and learn the Constellations.

 

Perfect for kids (and parents), Hotels, Motels and B&Bs.

 

Nightsky Ceilings are known for their authenticity, depth of perception and realistic 3D effect.  There are no stick on stars.  Check out the different effects and themes:

LESS  EXPENSIVE  MINUS  VIOLET  FILTERS

 

Minus Violet Filters can be used firstly, on short Focal Ratio Refractors to reduce the false colour which the less expensive brands tend to have.  Secondly, CCD Cameras require reducing the amount of Infra Red they accept for clearer images.  A Minus Violet Filter will do pretty well the same thing.

 

Minus Violet Filters $30AUD or $24US or £13

 

 

REFIGURING  YOUR  MIRROR

 

We currently have 3 experienced mirror makers who are able to refigure your current mirror.  If you have a Chinese made mirror which isn't up to scratch (yes, that's all of them), we are able to hand correct the optics and re-aluminise the surface with high quality coatings.  We have found the majority of mirrors have been overcorrected, have bumpy surfaces and errors, made by machine polishing.  If you want to know the difference it makes, pop along to an Astronomical Society viewing night, and have a look through a telescope who's mirror is hand made.

 

Let us know the size and focal ratio of your mirror, and we'll quote its facelift.

 

 

HAND  MADE  10"  F/5.4  DOBSONIAN

Made by one of the most experienced mirror makers in country,  this telescope has the highest optical quality.  Just for something different, we will accept bids for this telescope.  Bidding starts at $1100 plus whatever the shipping is to you.

 

 

BAFFLED  OVER  BAFFLING

There seems to be a bit of a debate about whether baffling is good for the telescope or not.  Having looked through a number and scopes, before and after, I have reached the conclusion that it does work.  Baffling doesn't need to be all the way down the tube.  There are programs available on the internet which tell you exactly where to position the baffles on particular telescopes, although, I have found the most benefit is to baffle around the secondary mirror and focuser area.

 

Terry Toweling still seems to be the best material to blacken a telescope, and stop those naughty reflections. Being fairly thick, it can be difficult to work with.  When adding any material to the inside of a telescope, unroll the material around the inside very slightly bunched, instead of trying to stick it flat.  This will help prevent the material from lifting, if it shrinks.

 

 

ANTI  VIBRATION  SUPPRESSION  MATERIAL

These really work.  Cut down how long it takes for the telescope to stop shaking.  Helps greatly in preventing outside movement from shaking your telescope.  Don't bother paying $100AUD when we have the material for $45AUD or $35US or £18

 

 

FILTERS  FOR  JUPITER

 

Since Jupiter is coming into its full glory for the year Light Blue Wratten Filters are $15AUD or $11US or £6.

 

 

FILTERS  FOR  THE  MOON

 

A Neutral Density Filter is best suited for the Moon.  It reduces the light, but doesn't change the colour which other filters do.  ND Moon Filters $15AUD or $11US or £6.

 

 

WHERE,  OH  WHERE,  HAS  MY  RUSSIAN  SHIPMENT  GONE?

 

We are still waiting for the Russian shipment to arrive.  It contains a number of TAL telescopes, Maksutovs and Accessories.  One of the highlights will be the 2" diameter, 24mm Focal Length, 80° Field Eyepieces which, by reports, are a high drool factor for $330AUD or $257US or £138.  Bibs are optional.

 

 

DAVID  MALIN  IMAGES  AVAILABLE

 

David Malin, reknown for being amoungst the best astrophotographers in the world, has many of his images available as photographic prints.  A list can be seen here:

 

http://www.aao.gov.au/images/general/big_prints.html

 

If you wish to purchase through Telescopes and Astronomy, let us know which ones you're interested in and how many and we'll quote a good price.

 

 

POPULAR  2"  OBSERVATORY  EYEPIECE

 

Another high drool factor is Harry Siebert's 2" diameter, 36mm Focal Length, 70° Field, Observatory Class Eyepiece which has impressed a number of people.  They are currently $290AUD or $226US or £121.

TELESCOPES  FOR  HIRE

 

Most Astronomical Societies around the world have "Telescopes for Hire!".  Contact your local society or club for details.  We also have telescopes for hire for our local area - please inquire.

 

 

SOLARSCOPE  -  A  GREAT  EDUCATIONAL  SUN  PROJECTOR

Developed in France, the SolarScope allows safe observation and measurements (including rotation speeds) of the Sun.  The Standard Model projects an image about 80mm (3.1") in diameter inside the cardboard hood, while the larger Education Model delivers a 115mm image.  Both will reveal sunspots, thanks in part to glass optics mounted in quality molded-plastic and machined aluminium assemblies.  The company's multilanguage web site includes lots of information, as well as free downloadable activities specifically developed for schools and educatiors.

Standard Model $125

Education Model $175

Focal Reducer 0.6x changes the F/ Ratio of your telescope.  If you have an F/10, using the 0.6x Reducer makes it an F/6 (wider field of view, shorter exposure time).  This is particularly useful for Astrophotography and CCDing.  The 0.3x Extender screws into the 0.6x to reduce the Focal Ratio even more.  The 0.3x Extender is not recommended for observation, on some telescopes, as towards the edge of the telescope's view, the field is no longer flat (elongated stars).  This is not important for most imaging devices as they do not have a wide field of view.

 

STUDENT  &  JUNIOR  MICROSCOPES  IN  WOODEN  BOX  $120AUD or $93US or £50

Good solid construction, good imaging, smooth rack and pinion focusing and good reviews.  Schools, don't pay $250 for these little gems.  If you have Carton or Olympus etc Microscopes at your school, with broken rack and Pinions, contact us to see if we have a much cheaper replacement.  Your high quality Olympus or Carton etc microscope lenses will screw or slide straight in!

STARRY  NIGHT  PRO  5  SOFTWARE  $230AUD or $162US or £87

At our Astronomical Society meetings, we have the usual "What astronomical events are coming up" just like other clubs and societies.  For our society, astronomical events are shown using Starry Night Pro.  A number of people have been quite impressed with the realism of the software.  Instead of just dots for stars, the software shows the night sky as it really looks, including realistic terrestrial views for effect.  You can also take a spacecraft for a ride!  So we decided to order some in and sell them for a great price.  The following site has all the information on the software:

ToUcams

 

 

ToUcam - LONG  EXPOSURE  MODS  NOW  AVAILABLE

Contact us about modifying the Philips ToUcam and other similar cameras (Quikcam etc.) for long exposure.  Using free software from the internet, the cameras can be used very easily to take long exposures of the night sky capturing faint objects.  Stacking multiple images using Registax is also very easy.  Registax is also available free from the internet.  The modification includes a switch to choose between short and long exposure.

 

 

ToUcam - CHIP  SPECS  &  PRODUCTION  SPEC  SHEET

Let me know if you need these emailed to you.

 

 

ToUcam - GETTING  THE  BEST  SETUP

The best images can be calculated by using some simple formaulas.  These formaulas will determine the best resolution for your size and focal aspects of your telescope.  A very well explained web site can be seen here:

 

http://www.frankbrandl.com/htm/webcam.htm

 

 

ToUcam  - STACKING  SOFTWARE

A number of people have told me that the AstroStax software gives better colour of nebulaes than Registax (See below, New Version Of Registax).  Both are free downloads.

 

The ToUcam Forum is very popular for information:

 

http://groups.yahoo.com/group/ToUcam/

 

 

ToUcam - CLEANING  THE  CHIP

Here's some advice on cleaning the ToUcam Chip:


"For those new to the ToUcam, I myself have had good results by dabbing a q-tip in 99% IPA (isopropyl alcohol), applying a slight
amount of pressure and swabbing once/twice across the cover in one direction.  IPA does not etch glass, so rest-assured there is no danger of damage here (I work in semiconductors and specialize in films and etch).  I might add I store my ToUcam upside-down, sensor down with a fresh layer of plastic wrap covering the adapter (but how I wish I could store it in a fab/cleanroom:)...).
 

Never use acetone, for it can delaminate the glass cover from the package.

 

 

ToUcam - NEW  VERSION  OF  REGISTAX

Registax software, amoungst other things, allows images to be aligned and stacked on top of each other automatically.  A new version of Registax has been developed and pre-tested by a number of people.  The new version will be available in the week leading up to Christmas:

 

http://aberrator.astronomy.net/registax/

 

 

HANDBOOK  OF  ASTRONOMICAL  IMAGE  PROCESSING  WITH  AIP4WINH

Obtain the best images possible!

 

Work is progressing on a complete update of the book and software to take full advantage of the rapidly expanding astro-imaging universe. The projected publication date is mid-winter 2005.

 

For the past three years HAIP/AIP4WIN has provided thousands of astro-imagers with both a text-book-like introduction to the subject and powerful software that allows them to practice this cutting-edge technology. Since its introduction the software has been enhanced and now stands as a robust tool for the scientific imager.

 

Richard Berry and Jim Burnell are now working on a complete re-write of the software and to revise the book to make it ever more flexibile and adaptable to the ever expaning field of astro imaging. Top line here is what will the new AIP4WIN will feature:

Robust new core routines and revised code architecture support trouble-free operation and future growth and expansion. Our track record for support and upgrades unequalled in the field of CCD image processing software will continue unabated.

 

Based on precise floating-point math throughout, so pixel values can be as large as 10^32 or as small as -10^32, with 32-bit FP precision (better than 1 ppm precision and 64 decades of dynamic range).

 

Virtually unlimited ability to stack files and accumulate pixel value, or average to original numeric range without loss of data or signal-to-noise ratio. Unbeatable for stacking /processing H-alpha in low-signal operations.

 

Able to load and display images limited only by the available system memory on your computer, and undocumented limitations in the Windows operating system. Processing speed limited only by the speed of your computer's CPU and display subsystem.

 

Supports all valid FITS files using official NASA FITS support libraries, including 8-bit, 16-bit, and 32-bit integer and flating-point FITS files.

 

Supports 40+ import/export formats in monochrome and color, including the popular JPEG, TIFF, PNG, and BMP format.

 

Plus a revised and more powerful suite of image processing tools and functions

 

Plus much, much more . . .

40mm  WIDE  ANGLE  EYEPIECE  WITH  T  THREAD

We are now producing 40mm focal length eyepieces with T Thread on the end. The T Thread

enables many adaptors and T Rings to fit onto the eyepiece. A 40mm focal length

eyepiece has a large clear aperture (part you look through) widening the field of

view for a camera.

 

There are a number of advantages to the eyepiece. Firstly, a wide eyepiece

entry hole (clear aperture) of 26mm allows a wider field of view for the

camera. Secondly, low magnification, which doesn't spread the light of the

object as much. Magnification is derived by dividing 40mm into your

telescope's focal length in mm. Thirdly, other adaptors are not needed to

connect the camera to an eyepiece, only a T Ring thread. Fourthly, the

eyepiece can still be used as a 40mm.

 

The T Thread Eyepiece is $130AUD or $88US or £50

 

 

NEW  FREE  RONCHI  SOFTWARE

There are a host of Ronchi software programs free from the internet::

 

http://www.users.bigpond.com/PJIFL/ronchi_software.html

 

Ronchi (Ron-Key) Testers show the shape accuracy of a telescope mirror using a series of lines.  Ronchi Testers, and unassembled kits, can by purchased from us.
