Objects Session Notes
- Evening session (4.7 hours) - Main aims of the session were to acquire a selection of variable star, nearby star and comet targets and deep sky targets as cloud/showers allowed. - Session terminated early when skies clouded over and because of forecast for rain/sleet later in the night - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -4°C (min) - CCD Temperature: -25°C - Notes from 2021-01-06 >> -
