Still messing with the 5d until money can allow an atik or something around that area. 1 hour exposure all up 3 min subs no dark flats. Using 10" sky watcher black diamond, coma corrector (although i cropped) and orion autoguider. Think Ive blown out the cores any ideas on processing would be great just did some levels and curves
Hi Scott,
Just to provide some ideas on processing as requested. I agree that the cores of the galaxies are blown out so it has probably been pushed a little too much in curves. There is some background noise (grainy blue in colour) so running a noise reduction algorithm would help. There is a noticeable light gradient across the bottom right quadrant of the image that would benefit from running a gradient removal tool. I can see some colour in the galaxies so a less aggressive curves might allow this to come through.
Can you update your post with more information such as ISO settings. Your post indicates that there were no darks so future images would definitely improve by taking at least as many darks as lights. Star shape indicates that the tracking is ok though I notice some small star elongation in the bottom left corner possibly due to a fast focal length newtonian.
