It's like the power went out beyond the Moscow Ring Road, lol.

Overall, I liked the work, especially the detailed processing of the satellite galaxy, M101.
However, when viewing the image as a whole, I can't shake the feeling of a "funnel" in the center of M31. Perhaps it's because we usually don't see it "upside down," though in space, there is no up or down.
As for drawbacks, I noticed purple halos around the stars.

Pardon, I made a typo! Not M101, of course, but M110.

Thank you for the kind words! Looking at it now, I think I might have overdone the background a bit—it turned out too dark. As for the purple halos, that’s my sore spot… My refractor seems to insist they have to be there, but I’m hoping the new filters will help fix that.
