C/2022 A2 (PANSTARRS) - Comet     IC 1705 - Elliptical Galaxy with Type Ia Supernova 2023fa IC 1756 - Spiral Galaxy with Type Ia Supernova 2023Q IC 2005 - Spiral Galaxy with Type Ia Supernova 2022dwa NGC 1363 - Spiral Galaxy with Transient AT 2022ackv     UGC 2926 - Spiral Galaxy with Type II Supernova 2022acyd       - UGC 6608, C/2019 U5 (PANSTARRS), NGC 5548, AT2023fm,  AT2023ds attempts failed (uneven illumination, due to snow & ice on front of telescope)     Variable Stars (photometric monitoring) - None        - SS Cyg, BL Lac attempts failed (uneven illumination, due to snow & ice on front of telescope)      Nearby Stars (astrometric monitoring) - None

- Attempted All Night Session session (12.3 hours) interrupted for 6 hours by cloud & snow. Images from second part of session rejected because of uneven illumination due to accumulated snow having slid off shutter onto front of telescope when shutter was opened upon session resumption.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -2°C (min) - CCD Temperature:  -25°/-30°C - Notes from 2023-01-16 >>
