Session Notes

Moon Jupiter - Planet Jupiter Moons     C/2014 Q2 (Lovejoy) - Comet     Tombaugh 5 - Open Cluster     Photometric Monitoring - Variables   - IW And, Z And, CZ Ori, FU Ori, RR Tau     Astrometric Monitoring - Nearby Stars   - Groombridge 34     Solar Eclipse 2015-03-20

- Evening session (2.3 hrs duration).   First session with new filters : BVRI,  Xo (Blue-Blocking Exoplanet), S (Star Analyser 200) and Nd (1.5% Neutral Density). - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  Temperature falling progressively to minimum of -2°C before rising to 0°C as cloud began to develop. - CCD operation -30°C (at 68% average cooling).  - Main objectives of the session was to monitor selected variable stars & nearby stars and to take gallery images of a range of deep sky objects.   -   - Focus Offsets for new filters determined during a short session three nights beforehand (2015-03-21). Flats for new and existing filters taken the following day (2015-03-25).
