It turns out to be a very difficult object to process...
But I figured out how to work with masks, everything was automatically overexposed if I wanted to stretch the wings. That is, two options: either the wings are white in the center, or no wings but the center is normal.
I made two stretches: one with wings, the second the center, then masks, and then addition in PixelMath. Of course, all actions without stars, working only with the background.

Добавил еще водорода с кислородом и отснял звезды в RGB, конечно они пухляшки и их много, но они появились в центре, в предыдущей версии их не было видно.

Очень оказывается не простой объект для обработки... Но зато понял как работать с масками, на автомате все выходило пересвеченным если хотелось крылья вытянуть. Т.е. 2 варианта или крылья центр б...

How great is the ultimate! I'll get one too. You did well for such a short time. Clear skies.

The processing is exactly as described. It's a very, very bright object. That's why I have 11 hours of integration data waiting for me to master HDR in PixInsight. I don't remember the exact name of the tool, but it automatically creates as many smart stretches as needed, and it's done with literally one "Make it pretty" button. If I'm mistaken about anything, please correct me.

Well, I'm not sure, I couldn't get it to work automatically, and of course I tried HDR.

I also haven't found such a super smart script. There is an automatic stretching feature, but it still needs a lot of work.

Thanks, I'll need to add and shoot the stars separately as well, since they're almost invisible in the center.
