NGC281 Pacman Nebula #6

I continue to accumulate Pacman. Only 3 hours. Minimal processing, all in Siril (remove background gradient, remove green noise, auto histogram correction, move black point to 0.05).

What is noticeable:
1) Stars are not burning out, but there are too many of them, will have to remove or shoot a star layer with shorter exposure.
2) Degraded zones are noticeable on the sides due to dithering. They will need to be removed.
3) The lower left corner is heavily overexposed or otherwise vignetted. At the same time, I performed background gradient removal for both single frames and the result.
4) Color is not calibrated, as is.
