This is another first light image (technically second) with the new APS-C color camera from QHY. I was ruined by clouds before I could get more data, but I don’t think it mattered much.
I attempted to compare two of the read modes to see if there was any difference but I couldn’t discern any that couldn’t be attributed to changing seeing condition or being higher altitude in the sky. This is a combination with part of the frames in High Gain mode (30 of them at gain 0/low conversion gain mode), and Photographic Mode (36 of them, also gain 0).
