Session Notes

C/2022 E3 (ZTF) - Comet     NGC 1501 - Planetary Nebula (PLN 144+ 6.1)         Variable Stars (photometric monitoring) - None      Nearby Stars (astrometric monitoring) - None

- Evening session (5.8 hours) hampered by condensation inside  the LX200 Telescope Tube, surpressing stars coming to the SBIG Camera, prevented the planned automated operations and make some user directed tasks like resetting telescope pointing and performing a short mapping job very difficult. Some images captured using the TS80 secondary scope with its ZWO 178MC Camera     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 2.0°C (min) - CCD Temperature:  -20°/ -25°C - Notes from 2023-02-04 >>
