Objects	Session Notes
29P/Schwassmann-Wachmann - Comet     Variable Stars (photometric monitoring) - None      Nearby Stars (astrometric monitoring) - None	- Very Short Session to acquire images of 29P/Schwassmann-Wachmann using Ad-Hoc Target submission, but hampered by cloud and threat of rain/snow.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 0°C (min) - CCD Temperature:  -25° C - Notes from 2022-12-07 >>
