Session Notes

NGC 7209 - Open Cluster (H VII-53) Du 1 - Planetary Nebula (attempt) K3-83 - Planetary Nebula (PLN 94- 0.1) C/2018 W2 (Africano) - Comet     Variable Stars (photometric monitoring)   - RX And, U And, Z And, BL Lac     Nearby Stars (astrometric monitoring)  - HH And, 61 Cyg, Groombridge 34, EV Lac

- Post-midnght session,  Duration 2.3 hr Session operated in fully automated mode, with initial monitoring only. - Main aim of the session was general observing with mix of variable stars, nearby stars, comets and deep sky targets.      - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  10.5°C falling to 8.5°C (min) in observatory (outdoors 1 to 1.5°C cooler,  Dew heaters on auto, ~ 90% power ) - CCD Temperature:  -15°C  (69% av. power) - Notes from 2019-08-20 >>
