- Night session (4.4 hr). Moderate seeing.. - Operated in semi-automated control. - Ambient Temperature 9 deg steadily falling to 4.5 deg C (minimum) - CCD operation -20 degC (at 64% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis.
