This is my first attempt at M31.

 

Scope:  Astrotech 60ed w/ 0.8 reducer

Mount:  ZWO AM5

Camera:  ASI533MC

Filters:  UV/IR, Optolong L-Ultimate

Processing in PI and PS

Site:  Atlanta, Bortle ~8

 

Subs:

   Broadband:  Baader UV/IR CUT Luminance (CMOS Optimized) 2": 207×180″(10h 21′)
   Narrowband:  Optolong L-Ultimate 2": 80×300″(6h 40′)

 

 

 

There is not a lot of narrowband in M31, but you can see some nebulae in there.  I'm pretty happy with this now.  There are some parts I'll quibble with, but that's a problem for the next attempt.  I'm putting this version to bed.

 

Thank you for looking!

Thats an excellent imasge- well done!

 

When you write not much narrow band in M31 that may be true for OIII and SII however, there is a lot of HA that can be captured- M31 is qute rich in HA. Very long integration times have also revealed a band of OIII that is not normally revealed. I guess a lot of targets may have hidden gems if we expose long enough.

Wow. This is way better than anything I’ve ever been able to do. Great work.

This is simply wonderful

That’s a really nice capture. You balanced the Ha well, mine always seems to overpower the image when I blend it in. Nice job.

Wow, awesome rendition! ...and the star-like nucleus is still (barely) visible!!!

 

You might not realize it but, as a nice bonus, you also visibly captured 60+ globular clusters within M31.

 

Now, your mission, should you choose to accept it, is to track them all down and label them with their appropriate numbers.

Funny, I actually started that with the first nights subs. When I was still looking through eyepieces, I used to track down as many of them as I could visually. It’s crazy how many of them are visible so far away.
