I wanted to share my latest attempt at M31, using an uncooled Nikon D7200 - fully processed with Pixinsight of course 
Image: mosaic of four panels, each panel 40x300s calibrated with bias, flat and darks
Image train: Skywatcher Equinox 120ED, 0.85 reducer, optolong L-Pro filter, modified Nikon D7200
Observation site: Bortle 4, 830m above sea level
Ambient temperature range: 15 - 20 degree Celcius
as the original file is 18MB, I had to compress the posted image substantially, causing some loss in crispness and detail.
