C/2022 E3 (ZTF) During Orbital Plane Crossing, 2023-01-23
Not a pretty night with clouds covering the early evening sky. I set the scope to run, using SGP, automatically to start at 0100 for hopes of the sky breaking. Being restless, I could see no clearing as the time approached start time, so I set the scope to run at 0300. As I drifted off to sleep I awoke the next morning to find a batch of usable 22 x 45 second subs, the rest were spotty with a few images being okay to be used for the starfield. Colors are off and framing is bad, but hey, I was able get the crossing event.
