Finally figured out the stars — the whole problem was in the crooked stacking in DSS. In PixInsight I couldn't stack, so I had to learn Siril. For a long time I didn't understand why it gave a directory error until it hit me that I had to write out the full folder paths). It's worth noting that after getting the image in Siril, the scripts in PixInsight started working properly during processing. I don't know how to describe this excitement — turns out I was just messing around with nonsense before this).

The stars are a real problem. I can't shake the feeling that something is wrong with the lens, or maybe it's just a lack of experience in processing.

Well, and probably we need to properly orient the object (mirror and rotate it).

In my excitement that I managed to stack it in Siril, I completely forgot about the geometry. https://drive.google.com/file/d/1X9A7D-T5a6wsT8f_KL8ou-wEkJbl6xJG/view?usp=sharing
