I struggled a bit with the background on this one. It seems if I do any noise reduction at linear stage with data fro the 2600mc, I end up with nasty red blotchy background. So this is just a gently TGVD after stretching.

 

SW Evostar80ED, NEQ6, ASI2600mc 160 x 120s

 

Suggestions for improvement appreciated.

I noticed with my 1600 doing noise reduction on the LRGB in the linear state produces awful results, so I tend to apply either TGV or MultiScale MedianTransform in the non-linear state, after colour combination. Strangely enough, noise reduction on NB images in the linear state works fine.

That is a lovely nice image, good job!

 

Did you use any filter with the camera?

Thank you. No filter, Map says bortle 4 but with sodium street light close to my boundary
