Description

Another one for my Messier list....

LRGB data aligned and stacked in MDL5, then post processed LRGB stack in IP65 without any split star procedure, mainly to see what I've got. I may try processing each channel separately before combining, to see if that improves the final image, but this one didn't turn out too bad. I had excellent guiding for most of the session with total RMS averaging sub 0.4', with long periods closer to 0.3', hence the nice round stars.

Vers B - tweaked colour balance as I thought the original looked unnaturally blue
