About this image

I have had some problems with the processing of this image and have just restarted from scratch. It is usual to add some of the Ha to the red channel but I prefer the contrast of the nebula against the colourful stars just using Ha as a luminance. It is easy to see where Gamma CAS is located with its glow and effect on the nebula.

Processing in Pixinsight.
