Session Notes

C/2018 N2 (ASASSN) - Comet     NGC 7479 - Spiral Galaxy (Caldwell 44)     Variable Stars (photometric monitoring)   -RX And, U And, CI Cyg, SS Cyg, BL Lac, DY Per, GK Per, FG Sge, V Sge - Z And attempt failed due to cloud     Nearby Stars (astrometric monitoring)  - HH And, 61 Cyg, Groombridge 34

- Evening session (3.2 hours) Session operated with automated control with remote monitoring.   Session was stopped earlier due to developing high wind and the risk of issues associated with clocks going back at end of summer daylight savings. - Main aim of the session was to continue testing of new features and changes in AstroMain program and acquire 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  (68% av. power) - Notes from 2019-10-26 >>
