Session Notes

NGC 524 - Spiral Galaxy (H I-151) NGC 1513 - Open Cluster (H VII-60) 38P/Stephan-Oterma - Comet NGC 2126 - Open Cluster (H VIII-68) 46P/Wirtanen - Comet     Photometric Monitoring - Variables   - RX And, U And, Z And, SY Cnc, S Cyg, SS Cyg, U Gem, AM Her, RZ LMi, BL Lac, U Mon,  CN Ori, FU Ori, NV Ori, GK Per, RR Tau, SU Tau, ER UMa - AM CVn attempt failed (hardware)     Astrometric Monitoring - Nearby Stars  - DX Cnc, 61 Cyg, Groombridge 34, EV Lac, CN Leo, LAMOST-HVS1, Teegardens Star

- All-Night Session (7.7 hrs net) Session operated in fully automated mode, but monitored over remote connection for 1st half of session.   An unexpected / unhandled dome closure at 01:55 and a computer crash/reboot at 03:47 caused the lost of  4.5 hours of potential observing time. Sky quality good, good seeing. - Main aim of the session was to 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:  -7°C (minimum)  - CCD Temperature:  -30°C (68% av. power) - Notes from 2019-02-02 >>      - Aurora Images/Video from 2019-02-02 >>
