Thanks for your comments
No I didn’t use flats
I’ve tried various methods to produce good flats at various ADU with my 2600MC , white T Shirt , LED photographic light panel with variable illumination settings etc.. and the various flats I produced don’t really help much with dust donuts and vignetting. A lot of folk with the 2600MC have similar issues obtaining good flats that work.
So I resort to keeping my sensor spotless and use the Vignetting preset in the Gradient Wipe module of Startools
Mistakenly with this image I forgot to use the Vignetting preset and used the Narrowband preset in Wipe ( Vignetting caused by full moon glare )
So to clean up the residual or trace of Vignetting in the image , I reprocessed the image using the Vignetting preset in Wipe
Here it is
Cheers
