Session Notes

Abell 39 - Planetary Nebula (PLN 47+42.1) Abell 70 - Planetary Nebula (PK 38-25.1) Abell 82 - Planetary Nebula (PLN 114- 4.1)     Jones 1 - Planetary Nebula (PK 104-29.1) M101 - Spiral Galaxy with Supernova 2011fe     NGC 1 - Spiral Galaxy NGC 6058 - Planetary Nebula NGC 7000 - Nebula ("North America Nebula") Photometric Monitoring - Variables - U And, W And, Z And, TT Ari, R CrB, CI Cyg, SS Cyg, U Her, BL Lac, DY Per, GK Per, FG Sge, U Sge, V Sge, WZ Sge     Astrometric Monitoring - Nearby Stars - Barnard's Star, 61 Cyg, Groombridge 34, And, EV Lac, Teegardens Star

- Evening session (6.0 hrs duration).  Good conditions - Session operated under semi-automated control, with remote monitoring from indoors computer.   Successful first use of Power-Line networking (no drops out for whole of session) - Ambient Temperature: -3.0°C (minimum)  Dew/Frost requiring corrector plate to be cleared with hair dyer on 3-4 occasions. - CCD operation -25°C (at 55% 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  -
