103P/Hartley - Comet NGC 6888 - Nebula (Caldwell 27) NGC 6189 - Spiral Galaxy & Supernovae 2010gl Double-Double - Double Star (Epsilon Lyrae) NGC 7331 - Spiral Galaxy (Caldwell 30) Jupiter Variable Stars Photometric Monitoring - Variables - RX And, U And, W And, Z And, R CrB, AM CVn, CI Cyg, SS Cyg, AM Her, U Her, BL Lac, CY Lyr, TZ Lyr, RU Peg, GK Per
CY Lyr attempt (too faint), DY Per (link ?)Astrometric Monitoring - Nearby Stars - None
- Night session (3.3 hrs), variable wind, ended when cloud cover came over. - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: 12.5 deg C (minimum) - CCD operation -20 degC (at 86% average cooling). - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis, and to acquire my first image of comet 103P/Hartley -
