The Andromeda Galaxy. The last time I photographed Andromeda...

The Andromeda Galaxy. The last time I photographed Andromeda (M31) was 2015, maybe fall of 2014? It’s been a while. I was using a DSLR–that was the only camera I had, and I had it on a terribly-used Celestron CG-5 equatorial mount with some aftermarket RA/DEC motors. By “terribly-used” I mean you could drive a truck through the gear backlash. Even so, I still managed to get some decent 30-second exposures of Andromeda, Orion Nebula, and other big bright targets in the sky. Well, I’m back with our galactic neighbor, and with much better gear: 192 x 120 second sub-exposures, ZWO ASI071MC camera at -10C, William Optics GT81 APO, iOptron CEM25P EQ mount.
