M31 (again)

[Phillyo]

It's an old favourite but each year I like to try and better my previous years image. This year I managed to get out to a Bortle 3/4 area and collect about 9 1/2 hours of data in 60sec subs with my Risingcam IMX571c and Redcat51. I have lots of good data but I'm really struggling to do it justice! I'm going to approach this again and see if I can do better but trying to tame the core, get the colours right and also bring out the faint dust at the ends of the spirals is really very tricky! 

I've added the xisf also if anyone else wants to have a play with the data and share your result on this topic?

Try again!

Rather than make post about M31 I thought I'd just add another revision to this one, this time with added Ha data (Approx 6 hours only due to clouds).

It’s a beautiful image, but not sure what’s happened to the stars….. any ideas…it’s all over the image

I think I've pushed it too far. I'm trying new things with the edit but it's not working too well. I'll look again tomorrow 👍🏻

Tried another reprocess. The stars at the far corners are still showing a little coma I think, but looks a bit tighter perhaps?

Another edit of this target, with added ha. Work in progress still!

A lovely deep M31. I must admit I fell foul of not reading the whole thread, I read the first reply and zoomed in on the stars and couldn't see anything wrong with them.

I got there in the end.

Sorry that's my mistake. I removed the first two images and just replaced them with the updated version. It looks a bit confusing now I guess 😕

No worries, I should have seen the "Edited" comment at the bottom of the post.
