Hi to all!
A few nights ago, I shot the virgo cluster and Markarian's chain.
I am really happy with how the shot turned out as it was only 1h 29min (89 shots of 1min) integration which is (in my opinion) not enough to get a good pic.
The only thing that is seriously bothering me: very dirty star halos that just won't go away!
Here's the image in question: https://drive.google...iew?usp=sharing
The image has already been edited except for those halos as I just couldn't get them out !
The edit (and stacking) was done in affinity photo.
Anyone who knows how to fix this? (I tried defringing several times whit no good result)
Thanks in advance!!
My gear: EOS 2000D modded cam, Ioptron skytracker, Canon EF 135mm F/2.0, no filter
