Session Notes

37P/Forbes - Comet C/2016 R2 (PANSTARRS) - Comet     Hickson 83 - Galaxy Group (PGC 58559 et al) Hickson 89 - Galaxy Group (PGC 66570 et al)     M27 - Planetary Nebula (Dumbbell Nebula)     Photometric Monitoring - Variables    - RX And, S Cyg, SS Cyg, AM Her, CY Lyr, DY Per, GK Per, FG Sge, V Sge - Failed Attempts:   U And (schedule),  RR Tau (cloud)       Astrometric Monitoring - Nearby Stars   - None

- Night Session (4.3 hours duration) . Part cloudy, wind.  Session was ended when cloud/rain appeared from SW.  (Sky subsequently cleared - leaving a missed opportunity) - Main aim of the session was to take images of selection of variable stars, nearby stars and deep sky objects).  Secondary aims were to test a automated observatory operations under variable sky conditions. - Session was mainly conducted as a fully Automated operation - - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  13°C (minimum)  - CCD Temperature:  -10°C (71% av. power) - Notes from 2018-09-18 >>
