Description

HαRRGB combination of 1 Feb 2013 RGB with 11 Feb 2015 Hα. The R channel is 75% Hα, and was boosted 130% in the CS6 channel mixer. This same HαR was used as luminance at 60% opacity. The original RGB was a bit grainy, so perhaps I could do better with new data, but this is one of my favorite objects.
