- Evening session (6.2 hrs duration).  Moderate conditions, wind affecting some images  - Session operated under semi-automated control, with remote monitoring from indoors computer.   (Power-Line networking - no detectable drops outs in over 6 hours). - Ambient Temperature: -1.0°C (minimum)  No problems with dew at all during session - surprise ! - CCD operation -30°C (at 70% average cooling).   - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of deep sky objects  -
