Thanks, yes, the calibration went a bit off, noticed it at the last moment. Need to gather more oxygen, then I'll try to restack everything from scratch. Quite a tricky squid...
It's not about accumulation; you just need to apply a noise reduction filter to the high frequencies. This won't reduce detail but will make the image more pleasing. Something like this:

Andrey, I agree, that's much better; the pixels on the squid are gone. I haven't fully mastered the noise reduction tools yet—there are many, and at different stages. So far, I've only used them on the linear image before combining channels. Another mistake here is that I suppressed the faint stars to bring out the nebula, which left a lot of artifacts. And the background is completely uneven. More integration time wouldn't hurt here either; it was very difficult to pull out this squid, especially since the hydrogen is too bright.
