Objects Session Notes
NGC 7492 - Globular Cluster Hickson 93 - Galaxy Group (NGC 7549 et al) UGC 12613 - Irregular Galaxy (Pegasus Dwarf, Local Group) NGC 7814 - Spiral Galaxy (Caldwell 43) NGC 1491 - Nebula PGC 69457 - Galaxy with Gravitational Lensed Quasar (Einstein's Cross) NGC 7331 - Spiral Galaxy (Deer Lick Group, Caldwell 30) Photometric Monitoring - Variables - RX And, U And, W And, Z And, T Cr, S Cyg, SS Cyg, BL Lac, CY Lyr, GK Per, FG Sge, U Sge, V Sge Astrometric Monitoring - Nearby Stars - Ross 248 (HH And), Barnards Star 61 Cyg, Groombridge 34
- Evening session (6.2 hr). Moderate conditions cold - Session operated under semi-automated control with remote monitoring - Ambient Temperature: Unstable: Initial 4 degC falling to 0.0 degC then climbed to f2.5 degC, falling to 0.5 degC, then climbing 4.5 deg before end of session - CCD operation -25 degC (at 62% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire images of a number of deep sky objects - - Notes from 2009-12-04 (Polar Alignment adjustment)
