Nova Per 2020 - Nova (V1112 Per, AT 2020abap) AT 2021ckv - Type YSO Transient (GCVS PR Ori) IC 357 - Spiral Galaxy with AT 2021fyd (unconfirmed) NGC 3310 - Spiral Galaxy (Herschel IV-60) with SN 2021gmj UGC 3502 - Spiral Galaxy with Type Ia Supernova 2021cwc UGC 6930 - Spiral Galaxy with Type Ia Supernova 2020rcq Variable Stars (photometric monitoring) - None
Nearby Stars (astrometric monitoring) - LAMOST-HVS1
- All Night session (2.4 hours) - Main aims of the session were to acquire a selection of variable star, nearby star and comet targets and deep sky targets as cloud allowed - Session cut short by development of cloud at 22:45 which lasted until dawn. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 4.5°C (min) - CCD Temperature: -20°C - Notes from 2021-03-24 >> [ Local Files >> ] -
