Jupiter taken on 13th September 2002 about 03.00 UT. Exposure time 1/8th second.
Equipment - Orion Optics OMC 140, Canon PowerShot A10,
ScopeTronix Digi-T Mount, Celestron 17mm plössl eyepiece. Not a brilliant picture but the best I have taken to date.
If you look to the right of Jupiter you can just make out one of the Galilean moons.
After checking in Astronomy Now I believe that it may be Gannymede reappering from occultation. I supppose the lesson here is to take more care with my observation notes.
Why Saturn is easier to image than Jupiter is a mystery as its further away, but life is strange.
If you do know why please mail me as I'd like to know!
I've included two pictures here as the first is unprocessed and the second is the product of 21 images of a similar quality stacked together to form a composite image using AstroStack2-(written by: Robert J. Stekelenburg) . The raw images were taken on the 13th October 2002 at 02.12 UT. The equipment is the same as that used to take the image above but this time I added a Meade x2 Barlow lens between eyepiece and telescope.

To be perfectly honest I'm not sure which of the two images i prefer. I think a little more practice is required with AstroStack2 (and stacking a larger number of images) before I'm able to get the full use and benefit of the software.
Some of the images that are possible can be seen on AstroStack.com's homepage.
Although after having said all that either one is an improvement over the first Jupiter picture!
