About this image

Managed to image during a small break in the clouds. This seemed like a quick and easy target. I used APT / CdC to manage scope, camera and PHD2 for autoguiding. Images processed using Affinity Photo, but also Siril to enable photomteric colour calibration. I was pleased to see such a variety of coloured stars.
