Session Notes

168P/Hergenrother - Comet 260/P McNaught - Comet C/2010 S1 (LINEAR)  - Comet C/2012 K5 (LINEAR) - Comet     Mizar -Double Star     Hickson 26 - Galaxy Group (PGC 12613 et al) Hubble Deep Field (HDF) - North     NGC 1272 - Galaxy Cluster, "Perseus A", Caldwell 24) NGC 1555 - Reflection Nebula   Photometric Monitoring - Variables - FO And, RX And, U And, W And, TT Ari, KR Aur, CY Cnc, R CrB, CI Cyg, SS Cyg, U Gem, BL Lac, EV Lac, RZ LMi, CY Lyr, TZ Lyr, CN Ori, FO Ori, FU Ori, NV Ori, DY Per, GK Per   Attempts: Z And failed (wind),  S Cyg (wind)     Astrometric Monitoring - Nearby Stars - DX Cnc, Teegardens Star

- Late Evening session (4.8 hrs duration).  Good seeing - Session operated under semi-automated control, with remote monitoring from indoors computer.   (Power-Line networking) - Ambient Temperature: 0.5°C (minimum) - CCD operation -30°C (at 75% average cooling).   - main objectives of the session were to perform further software testing and to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of deep sky objects. Opportunity taken to acquire a follow-up image of Comet ISON (C/2012 S1) -
