this is my first go at shooting this iconic target. would appreciate any insight on how to improve this image. this is only a little over three hours of integration so i have more hours i'd like to add to improve detail in the darker less bright nebulosity. any suggestions on how to sharpen the nebulosity without sharpening the stars? i tried a few quick selection masks, ie not very sophisticated, but that didn't work so well. still had a lot of the bg stars selected.
A few things i note that i'll address in the next round of processing,
acquisition details:
Lights 103x120s
60 darks, dark flats, flats
WO GT81 w/.8 reducer
ASI294 mc pro camera (120gain, 30 offset)these are the defaults; cooled to -10; no filters
asi224 guide camera
HEQ5 pro mount
Astro Pixel Processor and Photoshop, phd2, NINA
bortle 4
i'm processing on a color calibrated mac pro. Lots of experience in landscape photography but only been doing AP for less than a year. I use APP and Photoshop for Processing.
thanks for any pointers you may have.

A few things i note that i'll address in the next round of processing,
- warm up image a bit, looks a little bluish
- brighten and add more detail to the surrounding nebula
- improve guiding
