Session Notes

NGC 2681 - Spiral Galaxy (H I-242) NGC 2244 - Open Cluster (H VII-2) NGC 2204 - Open Cluster (H VII-13) NGC 2628 - Spiral Galaxy (UGC 4519) NGC 2360 - Open Cluster (H VII-12 / Caldwell 58) NGC 2158 - Open Cluster (H VI-17) 38P/Stephan-Oterma - Comet NGC 2841 - Spiral Galaxy (H I-205)     Photometric Monitoring - Variables   - U Gem, RZ LMi, BL Lac, U Mon,  CN Ori, FO Ori, FU Ori, NV Ori, GK Per - RR Tau attempt failed (aborted)     Astrometric Monitoring - Nearby Stars  - DX Cnc,  EV Lac, LAMOST-HVS1, Teegardens Star

- All-Night Session (7.7 hrs net) Session operated in fully automated mode, but monitored over remote connection.  Just after leaving it unattended the observatory computer crashed/reboot at 23:50 caused the lost of 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 and to the Relay System for the Dome Controller     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  -0.5°C (minimum)  - CCD Temperature:  -25°C (68% av. power) - Notes from 2019-02-04 >>      - Aurora Images/Video from 2019-02-04 >>
