Description

Rev C is a blend of the best of the previous 2 images-the better blue of B and the nice colors and dust lanes of A.

Rev B is a complete reprocess from the ground up to fix the star bloat and increase the blue channel.

A LHaRGB image using the RGB as a synthetic L channel. My Canon 135mm f/2 lens has a bit of bloat in the blue channel for brighter blue stars thus they are a bit larger than I would of liked. I may re-shoot the blue and/or do a set of luminosity subs with the lens stopped down a little. This was taken from a suburban location (Bortle 4.5-5) thus is wasn't as deep as some.
