This gallery contains images from a modified Canon EOS 300D DSLR.  The modification was to remove the built-n UV/IR cut filter, so increasing its sensitivity to the H-alpha and infra-red wavelengths.

Images are in reverse chronological order, ie latest first.

In order for these images to be displayed properly, adjust your monitor so that all of the gradations of black to white in the following chart are distinguishable, especially the two darkest shades.  Generally monitor contrast should be set as high as is consistent with comfortable viewing, and then the brightness adjusted.  The darkest shade should appear black.

Canon EOS 300D Images

 
   
    The Eastern Veil Nebula in H-alpha, with the Orion 80ED.
First light with an Orion 80ED.  A closer view of the optical performance of this scope. NGC 6888, The Crescent Nebula in H alpha Baade's Window.  Looking through the Galactic bulge to the other side of our Galaxy.
The Trifid Nebula (M20) - RGB / H alpha composite. A colour/ H alpha composite of the Omega Nebula, M17. A colour/ H alpha composite of the Eagle Nebula, M16.
The Dumbell Nebula, M27, a planetary nebula in Vulpecula.  Set in a very rich star field. First attempt at a composite H alpha / RGB image of the Lagoon Nebula. Eagle Nebula, and open cluster M16.  Site of the "Pillars of Creation".
     
The Omega (or Swan) Nebula, M17 in hydrogen alpha.  Nearly 2 hours total exposure! The region around Eta Carinae in hydrogen alpha.  This is a mosaic of 4 frames that extends about 2 deg of sky lengthwise. The Trifid Nebula (M20) in hydrogen-alpha.  Only the emission part of the nebula is visible, the light of the reflection (blue) nebula being almost completely blocked by the filter.
     
Hydrogen-alpha image of the huge Lagoon Nebula.  A sprinkling of dark Bok globules are visible amongst the sheets of glowing gas. The huge globular cluster Omega Centauri.  In monochrome because of an error in taking the flat field frames! The Eta Carinae Nebula.  First light with an Astronomik Hydrogen Alpha 13nm filter.  This object appears no more than 30 deg above the horizon and is embedded in the skyglow from Singapore city.  Nevertheless, with the filter, there is abundant detail in the image.

 

   
The beautiful spiral galaxies M66 and M65 in Leo.  M66 is distorted from interaction with its neighbour. The Coma Cluster of galaxies.  Most of the objects in this image are galaxies - making up the richest galaxy cluster in the sky. The globular cluster M5 in Serpens.  I'm starting to experiment to see if ISO800 and shorter individual frames will give better image quality.  This is the first of the ISO800 images.
     
     
The Antennae Galaxies in Corvus, with supernova SN2004gt visible. The Virgo Cluster of galaxies, centred on M86, but more than 20 other galaxies visible.  A negative image reveals how large M86 actually is. The spiral galaxy NGC 2997 in Antlia.
     
Elliptical Galaxy M87 (NGC 4486), in Virgo, together with other galaxies in the Virgo Cluster.  This galaxy shows a jet emanating from it's core.  This jet is shown in a separate, enlarged, image.  The Eskimo Nebula in Gemini. The reflection nebula NGC 1999 with a dark nebula (Bok globule) superimposed.  This region is interesting due to the presence of Herbig-Haro objects (jets of material from new stars). 
     
Spiral Galaxy M96 (NGC 3368), in Leo.   Notice that the galaxy's dim halo is visible, as well as the numerous background galaxies.  Autoguided with GuideDog, through the SS2K's serial connection, enabling far longer exposures than before.  The Open Cluster M46, with the planetary nebula NGC 2438 embedded.  The famous Horsehead Nebula, just south of the Flame.  First auto-guided image - using a separate 700mm focal length refractor and my SAC7 through Iris. 
     
Continuing in Orion, the Flame Nebula, right next to bright Alnitak, the eastern-most star in Orion's belt.   The "Running Man" Nebula, NGC 1977 (actually 1973, 1975 as well).  Another beautiful nebula in Orion, just north of M42.  The Orion Nebula, M42.  A favourite object revisited.   For a detailed look at the central Trapezium region, processed to show features washed out in the main image, click here.
     
The galaxy M33 in Triangulum.  I was quite pleased that the nebula regions in this galaxy showed up quite well. An image of NGC 7331 together with the compact galaxy group Stephan's Quintet (near top right of image).  Taken on the same clear night as the images of NGC 7331 and the Pleiades, this image is of NGC 55 in Sculptor.  Large with some remarkably blue regions with young stars. 
     
Part of the Pleiades star cluster.  Some nebulosity is visible around the stars, particularly around Maia, the mag 3.9 star at bottom centre right.  This image of the galaxy NGC 253, was one of the first taken with the modified camera.  Much higher sensitivity is in evidence, even through a Celestron LPR filter to cut down severe light pollution here in Singapore.  This image of the M17, Omega Nebula was taken before removal of the UV/IR filter.
