Finally shot this after more than 6 weeks of non-stop clouds and rain. Transparency was still pretty poor, along with strong wind, but any new data is better than no data at all :-)
I used my DSLR data from last year (same telescope) to make a HaRGB version (Rev. B). Clearly, the poor H-alpha response of my old unmodified camera was a limiting factor in my imaging setup.
3 days later, I shot a small amount of OIII (14 minutes) and SII (16 minutes) in very poor skies. I used tonemapping to blend the 3 channels, and used Ha as a luminance layer (Rev. D).
The color balance was further altered to a more traditional gold/blue palette with the SCNR tool in Rev. E, along with a slightly stronger stretch.
UPDATE 10 Feb 2019: I started reprocessing some of my older data, went for a more natural looking palette this time and used a few new processing techniques.
