M31 Andromeda Galaxy LRGB+H-Alpha enhanced
As a result of doing the H-Alpha only image I also decided to re process my last image of Andromeda with an emphesis on it's HII regions.
The image consists of 2 minute combined with 5 and 10 minute exposures for the luminance, 5 and 10 minute exposures for the RGB, 15 minute exposures with QHY9C one shot color CCD and finally 22 x 20 minute exposures using H-Alpha filter with QHY9M monochrome CCD Camera.
