M31 Andromeda

Thanks, after almost a year off, my processing skills have gotten rusty—this one was tough.

The main target was a real devil to capture! It didn't even fit entirely in the frame. I want a similar shot for my own collection—I'll be using this work as my reference!

Thanks, the plan is to add color stars here (the nebulae and filter seem to be absorbing the entire visible spectrum) and Ha+Oiii to bring out detail in the galaxy.

Thank you! Yes, everything is working normally. I tried adjusting the back focus because something resembling astigmatism appears at the edges, but moving it closer or farther from the calculated 55mm didn't improve things, so I left it at the standard spacing. I kept this reducer from the 80mm Svbony.

I have an old (still blue) ED80 from Sky-Watcher and I'm puzzled about buying a reducer-flattener. The original one is no longer available, so I have to look for third-party options. SVBONY's price is more affordable. Thanks for the information.

As far as I understand, only the native lens can achieve the most beautiful results; everything else can be adapted to some extent, but with nuances regarding the stars.

I'm using the 503 102mm Svbony with the included extension tube, but there's no ring like for the 80mm. Still, it seems to do its job, though I'm just learning and don't have any decent shots yet.
