Reassembled my dream Andromeda, included in the stack frames that I shot in 2023 on the Tak. Ended up with more than 73 hours of data, of which more than half in hydrogen-oxygen. Managed somehow to pull out SDSO1 better, and the emission nebulae in the galaxy. I'm happier with this version than the old one. P.S. The little crosses are because my cable organizer on the RASA is like that =)

My longest work, which took 2.5 months, 12 clear nights, and almost 60 hours of selected raw shots. The goal was to capture so much that the desire to return to this galaxy would not arise again anytime soon. An additional goal was to somehow reveal the recently discovered oxygen arc. Well, what came out, came out.
