- All Night Session (11.3 hours duration) . Session operated in fully automated mode, but monitored over remote connection Sky quality moderate, some issues with freezing fog and frost - Main aim of the session was acquire images of a selection of nearby stars, variable stars and deep sky objects taking advantage of moderate weather conditions. Secondary aim was to test recent changes and additions to AstroMain program     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  -6°C (minimum)  - CCD Temperature:  -30°C (68% av. power) - Notes from 2019-01-31 >>      - Aurora Images/Video from 2019-01-31 >>
