Great shots you have! Here, the hydrogen was overstretched, which destroyed the details of the nebula. I think you've reached the point where it's worth moving the processing to PixInsight. Believe me, with proper processing, the photos will improve to the next level.

Hello. Thank you. Yes, here I processed it "on emotion," so to speak—I wanted a very bright image (I also overdid it with the exposure; it really should have been 250 or even 200 seconds, not 300 seconds). Later, I reworked it, but I liked that version even less. Then I simply combined these two versions, and that was it. PixInsight is a good tool; I tried the demo version, spent a long time figuring it out, and started to get somewhere, but then the demo license expired. I never quite got around to purchasing it.

I'll tell you a secret: you can find the old version 1.8 on torrent sites. The price of the original software is unaffordable for many, and few would dare to buy it without knowing it first, especially since mastering the program will take at least a month, for sure.
