Observing location
Bassingham, Lincolnshire
Skywatcher ED80
Pier mounted NEQ6
QHY IMG2PRO at -20 deg

Baader Ha 7nm and RGB filters
22 x 1200s Ha; 20 x 200s each filter RGB

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.
