Another go at it, using more Pixinsight tools. This is a OSC image with a 3nm dual narrowband filter. There is a lot of OIII data buried in the image which will be a future effort. My Pixinsight workflow (in order):
(Pre-processing): Subframe Selector, WBPP
(Linear adjust): DBE, BlurX, Image Solver, SPCC, NoiseX
(Non-Linear adjust): StarX, GHS on stars (nothing fancy) and starless, Recombine (screen) stars & starless, BlurX, NoiseX, Curves for saturation and drawing out some finer details.
