Fred, Most excellent work.
Exquisite details. I was amazed at the Ha data alone, but the RGB data has taken this image to the next level. I true imaging feat indeed. Bugger the stars, just clone them out. At this focal length and use of a small bandpass NB filter, you trying to maximise/focus on nebulosity details, not capturing "pretty" stars. This is what imaging is all about, to capture the essence of a target delivering an unforgettable view. I have tried, but continually fail. Hat goes off to you. Well done.
