Unhappy after my first edit, PixInsight strangely crashed on me last night, which gave me the opportunity to start afresh....
I'm happier with this now. A slightly more traditional "SHO" palette, with about 50% Green removed via SNR.
Stars were added back in, but this time, not RGB stars. I under-stretched the StarXTerminator extraction of the star layers of each channel, recombined them, took the green out then layered the back onto the final image.
Cropped for a better presentation.
And here it is, and now I'm done (for now... never happy)
As always, a higher res version of each is presented here:
Starless and
My God, It's Sort of Full of Stars.
