- Evening  session (6.3 hrs)., excellent seeing - Session operated under semi-automated control, with remote monitoring from indoors computer.  - Ambient Temperature: -3.5°C  (minimum) - CCD operation -30°C (at 63% average cooling).   - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis. - with dark skies and good-excellent seeing opportunity was taken to acquire images of a number of galaxies
