This is my first post in Astronomy and Celestial. I saw a post the other day on Jupiter and its moons and decided to give it a try for myself. I used a 500/4 with a 2x extender on my 40D (Wimberley mount, no tracking). The single image was tweaked in Aperture and noise reduced with Nik Define, and then cropped. Ohh, and this was shot in northern NJ, 12 miles from mid-town Manhattan, so not the best dark sky conditions.
I'd appreciate any comments and suggestions for improvement.
