Jupiter | ||

Pretty obvious what this object is. If you take note of the North Equatorial Belt, you will notice two prominent storms, and you can barely distinguish a third storm to the left of those. It is easier to distinguish in the second photo. It was a result of seeing these storms that I decided to hook up the CCD camara and try to get some photos. North is up in these images. | |

This image was taken roughly 5 minutes later. I feel this one is a bit better. The reason why is that Dr. Martin Gaskell helped by showing me how to edit some parameters to increase quality. The previous image was my first attempt at doing the same thing, and as you might be able to tell, it looks a bit darker, especially around the poles. But, practice makes perfect, so hopefully I will perfect it with future photos. Thanks for the help Martin. | |

| This photo was taken in the same fashion and with the same equipment as the ones above, except that there is a focal reducer being used in this photo, that brings the f-ratio down from f/10 to f/6.3. This was done so that the moons could be captured as well. Also, instead of a flannel shirt, there is a specially made circular wooden board with a hole near the edge that, when placed over the end of the scope, does essentially the same thing. It was taken at exactly 8:00 P.M. Central Time, on April 5, 2002. The names of the moons have been added to identify them. | ||

| The original drawing was made on May 2nd, 2003, at a club star party. The second and third drawings were made several days later after scanning the first one. While a group of us stood around waiting for Io to finally go behind Jupiter that night, I decided to make an attempt at drawing Jupiter. I used Dave Churilla's 10-inch Dob., but can't remember which eyepiece he was using (forgot to take note). The picture to the left is the original drawing. This was done at night, using a red flashlight. As a result of this, I didn't spend a lot of time on getting the shading drawn perfectly, which explains why the second and third drawings are a bit darker. | This drawing is the second version...redrawn on printer paper so the blue lines aren't there. After first adding the drawings to this page, I noticed a few differences between the original and this drawing. I hadn't compared the two side by side until then. I realized that in the second drawing, the angle was different, and the two moons on the right were positioned lower than they should. Plus, the amount of polar caps visible was a bit different (unequal) than the original. | This is the third drawing. I did this after first adding the photos to the page to correct the mistakes in my second drawing. However, I left all three up so that you can compare the diffences in each one. This third image, for some reason, looks a bit grainier. Might be because the paper was on my desk when I drew it, instead of resting on my notebook (softer). |
| In the upper band, there is a small white circle. It represents a small hole I saw in the band. It is hard to see at this size, so if you click here, you will go to a page that has all three drawings in their original sizes. The other thing to note is the slight differences in the two main belts in each image as a result of redrawing them. It is important to note that the first image has some shading that wasn't fully erased the night I drew this. Callisto was visible...and was out past Io, but was far enough out that I didn't draw it in. I used a program I have to determine which moon was Ganymede and which was Europa. I drew these between 11:30 and 11:45 CDT. | ||
