Session Notes

C/2017 T2 (PanStarrs) - Comet     CM Tau - Pulsar (Crab Pulsar)     Variable Stars (photometric monitoring)   - RX And, CI Cyg, S Cyg, SS Cyg, AM Her, BL Lac, DY Per, RR Tau     Nearby Stars (astrometric monitoring)  - DX Cnc, Groombridge 34, Teegardens Star

- Evening Session (3.3 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:  3.5°C (min) (Dew heaters on new automated control) - CCD Temperature:  -20°C  (65% av. power) - Notes from 2019-12-01 >>
