Objects Session Notes
C/2015 O1 (PANSTARRS) - Comet 38P/Stephan-Oterma - Comet 46P/Wirtanen - Comet Hickson 40 - Galaxy Group (PGC 27509 et al) NGC 3254 - Spiral Galaxy with Type Ia Supernova 2019np Hickson 64 - Galaxy Group (PGC 46975 et al) Hickson 62 - Galaxy Group (NGC 4761 et al) Hickson 80 - Galaxy Group (PGC 56588 et al) Variable Stars (photometric monitoring) - RX And, Z And, AM CVn, SY Cnc, S Cyg, AM Her, RZ LMi, U Mon, CN Orio, FO Ori, FU Ori, DY Per, RR Tau, SU Tau, ER UMa
Nearby Stars (astrometric monitoring) - HH And, DX Cnc, LAMOST-HVS1, CN Leo
- Evening / Night Session (6.4 hours duration) .
Session operated in fully automated mode, but monitored over remote connection.
- Main aim of the session was acquire images of a selection of nearby stars, variable stars and deep sky objects taking advantage of moderate weather conditions. Secondary aim was to test recent changes and additions to AstroMain program - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -3°C (minimum) - CCD Temperature: -30°C (81% av. power) - Notes from 2019-01-28 >>
