- Evening session (5.5 hrs duration). Generally clear skies but near full moon (97% phase) Wind very light.  - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Main aim of session was to acquire images of various deep sky objects including Deep Sky Challenge Objects from past editions of Astronomy Now magazine, that have not been previously imaged. - Secondary aim was to test out operation of observatory and it's primary equipment, 12" LX200 + ST-10 camera, after a gap of 8 months - Ambient Temperature:  0°C (minimum)   - Note: TS 80mm APO guide scope + ASI178MC camera were not used during this session - Notes from 2017-11-02 >>
