I still can't afford to get a bigger camera so I got to use what I got;-) Here is a luminance shot of M51 taken with a little ST-237A. 20 two minute shots with 16 dark frames subtracted. The scope is a NP-101 over mounted on a G11/Gemini. Autoguided with a ST-4 mounted on a converted finder scope. I didn't mean to take so many dark frames, but some idiot left the lens cap on the scope;-)
