Objects Session Notes
Hickson 56 - Galaxy Cluster (ARP 322) NGC 6791 - Open Cluster NGC 6765 - Planetary Nebula Mayall II - Globular Cluster in M31 103P/Hartley - Comet PLN 64+ 5.1 - Planetary Nebula ? or Be Star (Campbell's Hydrogen Star) Variable Stars Photometric Monitoring - Variables - RX And, Z And, R CrB, AM CVn, RS CVn, CI Cyg, SS Cyg, BL Lac, CY Lyr, TZ Lyr, RU Peg
Astrometric Monitoring - Nearby Stars - Barnards Star, 61 Cyg
- Late evening session (3.7 hrs), poor sky transparency, poor- moderate seeing. Session ended when sky conditions deteriorated further. - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: 6 deg C (minimum) - CCD operation -20 degC (at 63% average cooling). - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis, and to attempt acquisition of Mayall II and Hickson 56 -
