Session Notes

277P/LINEAR - Comet 398P/Boattini - Comet     Nova Per 2020 - Nova (V1112 Per, AT2020abap)     UGC 1161 - Spiral Galaxy with Type Ia Supernova 2020acch UGC 2528 - Spiral Galaxy with Type IIb Supernova 2020adnx     Variable Stars (photometric monitoring) - RX And, U And, CN Ori     Nearby Stars (astrometric monitoring) - HH And

- Evening session (4.9 hours) - Main aims of the session were to resynchronise Scope Position/T Point Model by performing a short mapping job and to acquire a selection of variable star, nearby star and comet targets and deep sky targets as cloud/showers allowed - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 1.5°C (min) - CCD Temperature:  -20°C - Notes from 2021-01-02 >>      -
