Captured the object on 03.08.26 and 05.08.26. Also shot this nebula with the Askar C2 (SII+OIII) filter to get the SHO palette, but couldn't pull that off. Needed to stack more in SII+OIII, plus I concluded the filter isn't great for this kind of thing.

Hello, did you do any inter-frame shifts?

Hello. No, I did. Unfortunately, these are stacking artifacts, since they are only on the right edge, and there was nothing like that when stacking in DSS. But in DSS there was a different artifact that isn't here :) In short, I need to re-stack all these frames later.

Got it, today I started learning Siril for stacking. DSS has become such a mess — and the better the material, the worse the stacking result in DSS.
