Session Notes

C/2018 N2 (ASASSN) - Comet C/2017 T2 (PanStarrs) - Comet NGC 2308 - Spiral Galaxy with Type II Supernova 2019vsq     Variable Stars (photometric monitoring)   - RX And, U And, Z And, S Cyg, SS Cyg, BL Lac, CN Ori, FU Ori, NV Ori, DY Per, GK Per, V Sge, RR Tau, ER UMa - CI Cyg attempt failed due to cloud     Nearby Stars (astrometric monitoring)  - None

- Night Session (5.1 hours) Session operated under automated control Session preceeded by PHD2 testing/tuning - Main aim of the session was to test a number of new program features and to acquire images of a selection of targets     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  3°C (min) (Dew heaters on new automated control) - CCD Temperature:  -20°C  (67% av. power) - Notes from 2019-12-03 >>
