UGC 118 & PGC 212483 with Supernova AT2019B 46P/Wirtanen - Comet NGC 3254 - Spiral Galaxy with Type Ia Supernova 2019np NGC 2628 - Spiral Galaxy (UGC 4519) C/2015 O1 (PANSTARRS) - Comet PGC 32384 & PGC 213739 - Spiral Galaxies NGC 6181 - Spiral Galaxy     Photometric Monitoring - Variables   - RX And, AM CVn, SY Cnc, R CrB, CI Cyg, S Syg, SS Cyg, U Gem, SS Her, U Her, RZ LMi, BL Lac, U Mon,  CN Ori, FO Ori, FU Ori, NV Ori, DY Per, GK Per, RR Tau, SU Tau, ER UMa     Astrometric Monitoring - Nearby Stars  - HH And, DX Cnc, 61 Cyg, LAMOST-HVS1, EV Lac,  CN Leo, Teegardens Star -DX Cnc attempt failed (due to a dome slew issue)

- All Night Session (10.6 hours duration) . Session operated in fully automated mode, but monitored over remote connection for 1s half of session. 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:  -6.5°C (minimum)  - CCD Temperature:  -30°C (74% av. power) - Notes from 2019-01-30 >>
