I'm having problems processing this image of M27 that I took last week. It's RGB only (when I add the L layer it really gets out of wack (stars really turn gold) It is Red-300,G-300,B-300, using a ST2000xm camera and a C11 tube.I'm stll a real newby at this CCD imaging, I know once in a while people like to play with images on the forum. PLEASE go for it!!! Thanks, Tom

HEre's my quick and dirty attempt. I am no expert in ccd imaging, but I believe that you need to reduce your exposure times on the green and blue channels. Ron Wodaski explains this pretty well in "The new ccd Astonomy" book.
