Tilt is a pest.
A tricky one to process as its such a large dynamic range. To my eye it looks overexposed slightly that washes out some contrast and makes the O111 areas less blue.
These Newts are proving to be quite the resolution machines if ungainly in form.

Thanks Greg
I tried the Repair module in Startools to correct the double stars ( their not so much tilted but doubled due to one of the 3 stacked sets being affected by coma corrector tilt , my hunch is the Oiii set ) but this algorithm is only successful on a singular star out of shape due to tracking , optics and so on … I don’t think any non AI stacking algorithm could correct 2 perfectly round stars side by side separated by a gap of anywhere between by 8 to 20 pixels which is the case here.
I’ve got Han from ASTAP looking at the issue to see if he can tweak the Alignment algorithm in the Stacking program but I suspect not.
I did apply more local contrast to this bright region but a little more may have helped.
Strangely enough I did crop nearly half the native size of the image to show the pillars in more detail which should result in a dimmer image as pixels are reduced , but it didn’t ??
I’ve never imaged with a refractor , always used Newts , sort of comfortable with Newts , all those back end accessories on refractors scare me , Newts are simple and do the job , even cheap ones like my mine ( I build my own carbon Newts and never spent over $1800 )
Thanks Again
