- U And, SY Cnc, RZ LMi attempts failed due to cloud or poor skyNearby Stars (astrometric monitoring) - HH And, Groombridge 34, LAMOST-HVS1, Scholz's Star, Teegardens Star
- LAMOST-HVS1 attempt failed due to poor sky
- Post-Midnight Session (6.0 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: Starting at -1°C (min) before rising to +1°C by dawn
(Dew heaters on new automated control)- CCD Temperature: -20/-25°C (61%/68% av. power) - Notes from 2019-11-17 >>
