Mike,
Nothing gets past the Strongman !!
In regard to that “embossed” look , firstly it’s not caused by Startools SV Decon module or the Sharpening module. More likely it’s the Flux module which I’ve only recently used twice. Obviously I was a bit too heavy handed with it especially when you’re seeing limited.
This unique ( non AI ) algorithm pin points features in an image that has recurring fractal patterns eg: Gas flows and Filaments etc… then through flux prediction , can plausibly predict missing detail in seeing limited data.

It’s an extremely powerful tool and in the hands of a bloke who images at 1050mm under B8 skies with average seeing, once you crop and zoom in close to those pillars as if your imaging at 3000mm , the Flux module can be very enticing to the point where you loose focus on real detail. It can get out of control !!!

Very good pick up Mike !!

In regards to the dust lanes and dark structures, the Sharpening module does tend to coalesce those wispy structures if you push too hard. At defaults it works perfectly Ok.

Agree a tad more Contrast would reduce that residual subtle glare

However, after being totally peed off about the issue with the tilt in the coma corrector, I’m so grateful in salvaging the data and processing some sort of half respectable image.

At least the colour is typical HST / SHO palette ( golden hues , blue hues and cyan hues )

Thanks for your analysis and comments

Attached is just the Ha image ( in synthetic luminance) showing all the stars pin point to edge of frame
Attached is a snap shot in the corner of the image after resultant composed SHO image ( double stars ) mainly on the LHS of the image after composing SHO data sets

Thanks for your comments
Much appreciated
