Objects Session Notes
- Evening session (3.1 hrs duration). - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: -3.0 degC minimum - CCD operation -30 degC (at 63% average cooling). - main objectives of the session were to acquire images of a number of Herschel 400 objects in Ursa Major. Secondary objective was to acquire images selected project stars for ongoing photometric and astrometric analysis. -
