Session Notes

C/2017 T2 (PanStarrs) - Comet NGC 985 - Spiral Galaxy       - C/2019 Q4 (Borisov), NGC 1614, NGC 3279, NGC 3454, NGC 3455, UGC 4596 & SHK-1 attempts failed due to cloud      Variable Stars (photometric monitoring)   - RX And, U And, Z And, S Cyg, BL Lac - TT Ari, SY Cnc, SS Cyg, U Gem, RZ LMi, CN Ori, FO Ori, FU Ori, NV Ori, RR Tau, SU Tau and ER UMa attempts failed due to cloud      Nearby Stars (astrometric monitoring)  - HH And, 61 Cyg, Groombridge 34, Teegardens Star, - DX Cnc, CN Ori, LAMOST-HVS1 & Scholz's Star attempts failed due to cloud

- Full night session (9.8 hours) Session operated with remote monitoring for first 2 hours.  Sky effectively clouded over after 3 hours and session should have been suspended, but this was high cloud and was not readily picked up by the Cloud Sensor (clarity values didn't drop below 28) . - Main aim of the session was to test automated SharpCap imaging capture and integration with AstroMain /PHD2 and acquire selection of targets     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  Falling from 2°C to  1°C (min), before climbing to 4°C due to developing cloud. (Dew heaters on new automated control) - CCD Temperature:  -20°C  (61% av. power) - Notes from 2019-10-25 >>
