Description

Finally after 2.5 month of clouds and wind and only short sessions with 4 or 5 lights,  I got one complete night on M31. 
Ha data extracted and added with Pixel Math, Lum data processed after Tim Hutchison.
Pixelpeekers will discover some minor deringing around some stars.
The final image is cropped to show the detail.
Lum is 399x20sec = 2h13min.
I'm not sure why I took 600sec Ha for 4 hours. i guess I missed it in NINAs "Advanced sequencer" ;-)
