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;-)

Ralph, that is just superb! The small pixels in that camera appear well suited to this type of work. The detail you have captured is just incredible. Nicely done.

You have a great start there, Ralph. I think if you got two more 20 minute subs you could really smooth that out. At least you wouldn't need more darks. If you do add to this image, make sure you post it to us.
