Revision title: Different approach to processing of separated stars and nebula

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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
