M31 is the main subject, with NGC206 the blueish patch top-left a cluster of young stars, M32 top-center and M110 truncated bottom-center satellite galaxies.
After a failed attempt last year, I restart this subject on my newton with higher exposure, better framing, and the EQ mount which should allow not to drop too much borders (the alt-az moves were too big and random for this very wide subject).
Framing isn't perfect, as I caught the wrong diagonal to get M110 entirely in the frame. Must remember this next time – though on the field it may be difficult to tell which side is which.
This intermediate result is now much better than last year, and starts to show details.
