Description

This is the first image processed mostly in PixInsight with just a couple of excursions into GraXpert and Topaz AI Clear.  After a lot of practice I managed to get GeneralisedHyperbolicStretch to do what I wanted and was pleased with the results.  The processing flow was:
WBPP2 - GraXpert - LinearFit - PSFImage(in preparation for) - BlurXterminator - StarXterminator -  NEBULA separate S2, Ha and O3 - MultiScaleLinearTransform (denoise) - GeneralisedHyperbolicStretch) - Pixelmath straight SHO to RGB -  STARS - Pixelmath straight SHO to RGB) - Linear stretch - SCNR (green and magenta) - GraXpert  - PIXELMATH Max(Stars,Starless) - Gentle adjustment of luminance and saturation using Bill Blanshan's colour mask tools - a bit of MultiScaleMedianTransform (denoise) - Topaz Studio AI Clear to finish.
