Session Notes

C/2018 N2 (ASASSN) - Comet SHK 1 - Faint Galaxy Group     Variable Stars (photometric monitoring)   - RX And, U And, U Gem, FU Ori, SU Tau     Nearby Stars (astrometric monitoring)  - DX Cnc, Teegardens Star

- Evening session (6.5 hours) Session operated under automated control with 'smarter suspension' handling to take advantage of clearest intervals and suspend the sessions when conditions are too poor to be useful based on Stars Count from the AllSky Camera (rather than just using Clarity reading from the CLoud Sesnor) r. - Main aim of the session was to test the new smarter suspension handling and acquire a selection of targets if conditions allowed.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  2°C (min) (Dew heaters on new automated control) - CCD Temperature:  -20°C  (63% av. power) - Notes from 2019-10-29 >>
