29P/Schwassmann-Wachmann - Comet C/2020 V2 (ZTF) - Comet C/2022 E3 (ZTF) - Comet     IC 1874 - Spiral Galaxy with Type IIP Supernova 2023fu M31 - Spiral Galaxy with Type FeII Transient AT 2023ax  (Attempt / Unconfirmed)     UGC 3044 - Irregular Galaxy with Type II Supernova 2023cf      -  NGC 2283, IC 1756, NGC 1363 & 81P/Wild attempts failed (due to cloud)     Variable Stars (photometric monitoring) - BL Lac      Nearby Stars (astrometric monitoring) - None      -  Groombridge 34 attempt failed (due to cloud)

- All night session (10.7 hours) interrupted by and affected by cloud This was a "return to normal service" session following problems with condensation/dew inside the telescope tube since snow slid off shutter and fell on the front of the LX200 telescope 3 weeks ago (S1088, 2023-01-18), which have now be resolved.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 8.5°C (min) - CCD Temperature:  -10°/ -15°C - Notes from 2023-02-10 >>
