Description

This was first light for the ZWO ASI071 OSC camera. Skies at the 2019 RAC Summer Star Party were clear and fairly dark but we endured very high humidity all week. Guiding was terrible, with RA bouncing up and down more than 4 arc seconds all night. Because M31 is so large, I could not crop out the eccentric stars around the edge. Next up - a field flattener.
