I know this image is not near as nice as Megrac's from a couple days ago, but decided to post it anyway. The ED80 just doesn't have the light gathering of a medium size reflector. One hour 21 minutes of lights at 3 minute exposure, 40 darks, and forty flats. No bias or dark flats were used in the processing as they tended to create lines in the background. Comments good or bad are welcome.....Greg

I think that M104 is one of those things that we've seen so many good images of that we forget how small and difficult it is.
Your image desperately needs a color balance adjustment.

Thanks Steve, here is what I had to work with. Perhaps I need to not balance, but reduce the green?

Tell me about it! This image is one of maybe a dozen attempts to get close to what I wanted. Reprocessed the stack in DSS several different ways trying 2x drizzle and 3x drizzle, bias or no bias, added 14 more darks, tried selecting only the best lights for the stack. Tricky is an understatement Raymond...:)
