I picked up a small low res camera that could fit in my telescope's eye piece, and was pleasantly surprised what ten minute exposures and stacking software could do.
Although a little fuzzy I was pleased to see that the stacking software was able to show Saturn's shadow on it's rings.
I was REALLY pleased with this picture of Jupiter. You can see the gas bands and all. Perhaps I can get a suitable antenna up to listen to what emissions it might have for us.
