Description

2hrs 47 mins on Andromeda galaxy.

Still getting elongated stars towards the corners; will try some extra backspacing.

It was a cold night when imaging, a few degrees below zero; ASIAIR was reporting 2-3C (I think for the camera) which will have helped keep noise low.

Title: revised

Description: The result of an afternoon's experimentation in Affinity Photo 2. Some gradients and artifacts remain, but overall a big improvement. Much use made of James Ritson's macros. A lot more still to learn, and looking forward to reprocessing old data.
