Session Notes

C/2018 Y1 (Iwamoto) - Comet     Photometric Monitoring - Variables   - SY Cnc, FO Ori, NV Ori, RR Tau, FU Ori, U Gem Z And, AM CVn, Z attempts failed due to dew     Astrometric Monitoring - Nearby Stars  - DX Cnc Groombridge 34, CN Leo attempts failed due to dew

- Short evening session,  Duration 1.1hr Session operated in  fully automated mode, and monitored over remote connection. After a promising start cloud rapidly rolled in and brought the session to an end. - 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:  -1°C (min) - CCD Temperature:  -20°C  (70% av. power) - Notes from 2019-03-18 >>
