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

Hi thanks for the answer! My cam has a built in filter that takes care of the uv tho... is it still a problem then?

What software are you using? If it's PI I may be able to help.

 

EDIT; sorry...I see you are using affinity photo. I cannot help with your software since I used PI to tackle a similar problem.
