Постарался сберечь больше деталей в центральной области и другая работа со звёздами - теперь их нормально видно и поверх туманности.

Nice! It would be great if the January version could also protect the nebula's core from being overexposed, just like in the August version.

Thank you! Yes, I'll need to try and figure out the issue with the star halos.

Posted a new version where the center is not as blown out. Plus, different star processing.

Great result! I'm not an expert in processing, but maybe try using a mask in GIMP to tone down the bright center and slightly increase the brightness of the outer parts? I'm also amazed that with such light pollution, you managed to bring out the dark parts of the nebula! My light pollution is about the same, and I couldn't pull them out. Only when I went out of town was I able to reveal the dark parts even a little.

Vladimir, thank you! I could probably try to do something more with the bright core, but I've already reached the limit of my skills :)

I've described the processing step-by-step on the forum: https://astronomy.ru/forum/index.php/topic,51569.msg6241609.html#msg6241609 Perhaps some parts might be useful to you as well.
