Objects Session Notes
- All Night session (11.4 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, acquire images of the gravitionally lensed quasar known as Andromeda's Parachute and to test new feature and bugs fixes in AstroMain 3.35.9 - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -4°C (min) - CCD Temperature: -25/-30°C - Notes from 2021-02-18 >> [ Local Files >> ] -
