- Evening Session (3.7 hours duration) . Poor sky transparency - Main aim of the session was acquire images of a selection of nearby stars, variable stars and deep sky objects , and perform software testing.'     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  -2.5°C (minimum)  - CCD Temperature:  -25°C (70% av. power) - Notes from 2018-12-16 >>
