Alex,
Attached is my image of NGC 6744 Pavo Galaxy captured down south from my Dome with the 10” Carbon fibre Newt and EQ8-R mount
5 min subs at Gain 0 ( 3 hours of data with calibration frames Flats and Bias )
The 4 images show the progression in processing with Startools 1.8 from original untouched Star field to using Shrink ( tighten ) , then Dim Small ( Superstructure) then Isolate ( Superstructure)
Also attached is a photo of my Star mask I used for all Star reduction processing
You see a massive reduction in Star brightness from original to final
I’ll post a separate workflow for a Star Mask , Shrink , Dim Small and Isolate
Oh just a question which version of Startools are you using , hopefully version 1.7 or the latest version 1.8 ?
Cheers
Martin
