I am bug a beginner and I have a DYI mount which is not yet very good.
Yesterday, I tried to image ngc457, I have around 400 frames, but I have a slow drift of around ~0.4 pixel per frame. This means, after 200 frames that I have a 80 pixel drift.
The issue is that, siril seems to have no issue finding the proper star for the first 200 to 250 frames or so, but then, it seems to get confused and the registration seem to pick the “wrong” star, and my frames become badly aligned…
I am doing a 1 star alignement. When I try 2 stars, it drops (fails) on around 50% of my frames…
What can I do to fix this?
- Should I split my frames into 2 stacks?
- Is there a way to tell Siril that to “follow” a star during alignement?
- Would changing the reference frame help?
