Objects Session Notes
46P/Wirtanen - Comet NGC 201 - Spiral Galaxy with Type II SN 2019yc 
NGC 936 & NGC 941 - Galaxy Pair (H IV-23, The Tie Fighter Galaxy) NGC 1084 - Spiral Galaxy (H I-64) NGC 1999 - Nebula (H IV-33) NGC 1907 - Open Cluster (H VII-39) 38P/Stephan-Oterma - Comet C/2015 O1 (PANSTARRS) - Comet NGC 1528 - Open Cluster (Herschel VII-61) Photometric Monitoring - Variables - U And, Z And, AM CVn, SY Cnc, U Gem, RZ LMi, U Mon, FO Ori, FU Ori, NV Ori, DY Per, SU Tau
- CN Ori, ER UMa attempts failed (Cloud), FU Ori attempt failed (Aborted)
Astrometric Monitoring - Nearby Stars - HH And, DX Cnc, Groombridge 34, LAMOST-HVS1, EV Lac, Teegardens Star
-CN Leo attempt failed (cloud)
- Evening Night Session (6.9 hours duration) .
Session operated in fully automated mode, but monitored over remote connection, with interventions to resolve a Dome Slewing Issue
- 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: -4.5°C (minimum) - CCD Temperature: -30°C (74% av. power) - Notes from 2019-02-01 >> - Aurora Images/Video from 2019-02-01 >>
