Rick,
I have new green data and have been trying to make something of it.
Your level of wizardry with PixInsight is an order of magnitude higher than mine. I'm wondering, with our Background Neutralisation and Colour Calibration, howdo you select a ROI being that of the galaxy ... Given I have one image file open which is the DBE modified LRGB combined image, do I select that same image for the white and background reference? I'm doing this but not seeing any change in my image ... just a bit confused about how to use the tools
And second question ... Saturation Boost - what tool do I use for saturation? I can't find a process for it
Thanks!

I wouldn't normally use CC this way but I didn't have a master dark for my normal technique... probably would have been better to leave the cold pixels and clone them out later.
For the RGB the processing steps were: [L]RGBCombine, DBE (twice), BackgroundNeutralization, ColorCalibration (with galaxy as white reference), SCNR to reduce green, light TGVDenoise, stretch, ACDNR chrominance noise reduction, Luminance masked curves saturation boost, masked curves desaturate background.
I think the "magic" step was the saturation boost. There's usually plenty of colour lurking in these images but you have to drag it out (and sometimes you have to be more selective about what you do and don't enhance).
Cheers,
Rick.
