Color artifacts in stack


I encountered another (newbie?) problem.
I used Sirilic to stack two sessions of DSLR photos of M51.

The script went through without errors. During stretching of the stacked image, weird color artifacts appear.

Here’s the script straight from Sirilic: sirilic.ssf (3.6 KB)

What did I do wrong?

You obtain this artifact probably after background extraction.
You have an option to check in this tool to avoid this issue.

Where exactly?

Thanks, I’ll try later. :+1:t2:

Edit: It worked, thanks!

Every option has a tooltip that explain everything about it.
