And too the gradient is in the Andromeda shot earlier with H-alpha regions



How do i remove a circular gradient (is it from compression?)

Should I use NIK utilities?

or Topaz AI?

or are either one good for that?

I already god NIK utilities on my photoshop just need to pay for it

It was the same Andromeda shot taken on August 25th 2022 with my qhy600ph-c and my Celestron rasa 11" about 2.5 hours of Integration time
L-Pro filter...

all on a cem120ec2 mount

ps: I've got a Samsung Galaxy S22 ultra smartphone with 8K 24fps ability.

And a Dell xps 8950 and Dell 8K monitor...and observatory.
