- Late Night Session (3.3 hours total).
- Main aims of the session was to follow up on earlier supernova observations and acquire images of a selection of deep sky and comet objects - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 0°C (min)
(Dew heaters on auto)- CCD Temperature: -20°C (59% av. power) - Notes from 2020-04-28 >>
