Objects Session Notes
IC 65 - Spiral Galaxy & Supernovae 2009mf NGC 383 and adjacent galaxies ("Pisces Cloud") NGC 663 - Open Cluster (Caldwell 10, H VI-31) NGC 559 - Open Cluster (Caldwell 8, H VII-48) NGC 457 - Open Cluster (Caldwell 13) NGC 147 - Local Group Galaxy (Caldwell 17) IC 5146 - Cluster with nebulosity (Cocoon Nebula, Caldwell 19) IC 1613 - irregular galaxy, local group NGC 1027 - Open Cluster Photometric Monitoring - Variables - RX And, U And, W And, HR Aur, KR Aur, S Cyg, SS Cyg, AM Her, BL Lac, CY Lyr, FG Sge, U Sge, V Sge, RR Tau
RX And, Z And, TT Ari, DY Per, RU Peg Attempts (failed due to frost on lens, windshake or moonlight)Astrometric Monitoring - Nearby Stars - Barnards Star, 61 Cyg
HH And, Groombridge 34 Attempts (failed due to frost on lens)
- Evening session (5.8 hr). Cold, Stable seeing - Sessions operated under semi-automated control with remote monitoring - Ambient Temperature: Initially 1.0 degC falling to -1.5 degC minimum before climbing back to -0.5 degC by end of session - CCD operation -25 degC (at 55% average cooling). - main objective of the sessions 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, mostly updated/improved images of objects last imaged in 2005-2007.
