- Full night session, Duration 6.3 hr
Session operated in fully automated mode without any interventions and with limited monitoring
- Main aim of the session was a full night of general observing with a 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: Falling to 7.5°C (min)
Outdoors 1°C cooler than Observatory)
(Dew heaters on manual, 50% & 80%)- CCD Temperature: -15°C (67% av. power) - Notes from 2019-08-31 >>
