19P/Borrelly - Comet 132P/Helin-Roman-Alu - Comet Nova Per 2020 - Nova (V1112 Per) Nova Cas 2021 - Nova (V1405 Cas) AT2021agjs - Ulens? Transient NGC 2313 - Emission Nebula NGC 2761 - Spiral Galaxy with Type Ia Supernova 2021aggu NGC 7446 - Elliptical Galaxy with Type Ia Supernova 2021agdd UGC 4671 - Spiral Galaxy with Type Ia Supernova 2021afsj UGC 5528 - Spiral Galaxy with Type Ia Supernova 2022B UGC 8975 - Spiral Galaxy with Type Ia Supernova 2021adpe - UGC 1971 & UGC 1098 attempts failed (guiding failure/ LX200 Comms Issue) Variable Stars (photometric monitoring) - U Gem, CN Ori Nearby Stars (astrometric monitoring) - EV Lac, Scholz's Star
- All-night session 11.2 hours - Issue with slow LX200 Communications / Poor response during first part of session which was diagnosed to be due to experimental reading/charting of Scope Temperature via LX200 protocol request. Eventually resolved and the session was continued (at 21:57) , however by this time 3.5 hours of good observing time was lost. - Remainder of session interrupted by cloud & threat of rain. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 0.5°C (min) - CCD Temperature: -25°C - Notes from 2022-01-03 >> [ Local Files >> ]
