Objects Session Notes
38P/Stephan-Oterma - Comet 46P/Wirtanen - Comet CM Tau - Optical Pulsar (Crab Pulsar) M1 - Supernova remnant (Crab Nebula) M31 - Spiral Galaxy (part) NGC 2585 - Spiral Galaxy NGC 3254 - Spiral Galaxy with Type Ia Supernova 2019np SN 2018kag - Supernova Photometric Monitoring - Variables - RX And, U And, Z And, SY Cnc, SS Cyg, U Gem, RZ LMi, U Mon, FU Ori, NV Ori,DY, DY Per, GK Per, SU Tau, ER UMa
Astrometric Monitoring - Nearby Stars - HH And, LAMOST-HVS1, Teegardens Star
-DX Cnc attempt failed (due to a dome slew issue)
- Evening Night Session (6.3 hours duration) .
Session operated in fully automated mode, but monitored over remote connection, with interventions to resolve a Dome Slewing Issue
Sky quality good, good seeing.
- 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: -4°C (minimum) - CCD Temperature: -25°C (63% av. power) - Notes from 2019-01-23 >>
