Nice to see you found clear skys in your area for an excellent image of M31.
I like how you tamed the core :)

Hi Julian,

nice image, but it looks like there's big ringing artifact around the galaxy core. What did you use for HDR compression?

I used HDR wavelets, Linear interpolation, 6 layers, 1 iteration, lightness mask, no de-ringing or star mask.

Thanks for that. I have never imaged the M31 before and it is a bit of a jaw dropper when seen for the first time.

All the best

Julian

Julian,

Yes, thats one of the main effects of our beautiful hobby, we are seeing jawdropping stuff that "normal humans" can't see  :D
