- All night session (9.1hr). Operated under automated control for bulk of session, with remote control monitoring during initial 3 hours - CCD operation of -25 degC (at 69% average cooling). - main objective was to acquire images of certain selected stars for ongoing photometric, and astrometric measurements in particular Z And and RX And, plus a number of gallery images.
