- Night time session (3.8 hrs).
Initially clear sky with patchy cloud,
Condensation forming on front corrector lens at end of session- Operated using semi-automated control with remote monitoring - Ambient Temperature initially 12 deg C, decreasing to 8 deg C by end of observing session. - CCD operation -20 degC (at 71% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. -
