M20 Trifid Nebula Reprocessed

I wasn’t totally happy with the initial post of this image at the beginning of June so decided to spend some time on a re process
Same data ,same stack and still used Startools V1.5 Linear Data Set but tweaked a few things -
Stretched a bit more with Autodev but reduced shadow linearity
Bumped up Deconvolution and grew the mask a bit bigger
Increased Sharpening from 120 to 150
Increased Multiply 2 x gamma Correct to 20% in the Life Module increase detail in the Nebula and tone down the star field
Grew the inverted star mask a bit bigger in the Colour module to reduce the Orange Tinge halo affect around the star fields, particularly the smaller stars
Bumped up RGB bias in Colour module and Dark Saturation
Increased Noise Reduction Grain size from 4.5 pixels to 5.5 pixels and used 15% non linear response
Use Shrink module to soften the star field by 1 pixel

Anyway here it is after throwing another 3 hours processing at it
Don’t know if it’s ended up any better but it seems a bit cleaner and more defined than the original version
