Thats an excellent image Jeff, suprisingly deep, your being hard on your self, and the colour looks pretty good.

One thing you missed. ALL the detail of an image comes from the lum channel. The RGB can be relatively poor (as long as its not too noisy), the biggest improvement you can make to this image now is megadata on the Lum channel. The 1 hr or so exposure each on the RGB youve done is fine, just a tweak in PS on RGB saturation is all thats required (or if yr keen, blending lum into RGB to boost colour ). I would recommend you try a few more hrs just on Lum to allow more sharpening without noise appearing. Its not unusual to take 10 times longer exposure on Ha/Lum (for Lum channel) over RGB, not the equal exposures youve done. I have often taken 10 hrs or more Lum/Ha to go with 1 hr RGB exposures.
