Session Notes

C/2012 J1 (Catalina) - Comet C/2012 K5 (LINEAR) - Comet     Hickson 1 - Galaxy Group (UGC 248 et al) Hickson 20 - Galaxy Group Hickson 100 - Galaxy Group (NGC 7803 et al)     IC 1276 - Globular Cluster     NGC 1647 - Open Cluster NGC 2976 - Spiral Galaxy NGC 6229 - Globular Cluster (Herschel IV-50) NGC 6307 - Spiral Galaxy NGC 6934 - Globular Cluster (Caldwell 47) NGC 7674 galaxy group (Hickson 96 / ARP 182 ) NGC 7909 - Elliptical Galaxy ( ARP 150 / Hickson 95)     PGC 9159 - Spiral Galaxy PLN 164+31.1 - Planetary Nebula ("Headphones Nebula")   Photometric Monitoring - Variables - Z And, TT Ari, R CrB, CI Cyg, S Cyg, SS Cyg, BL Lac, DY Per, GK Per Astrometric Monitoring - Nearby Stars - HH And, Groombridge 34, Teegardens Star

- Evening session (5.0 hrs duration).  Moderate conditions, improving towards session end. - Session operated under semi-automated control, with remote monitoring from indoors computer.   Third use of Power-Line networking - no detectable drops outs in 5 hours. - Ambient Temperature: 2.0°C (minimum)  Dew requiring corrector plate to be cleared with hair dyer on 1 occasion. - CCD operation -25°C (at 73% average cooling).   - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of planetary nebula  -
