Objects Session Notes
C/2012 K5 (LINEAR) - Comet 168P/Hergenrother - Comet Variable Stars Photometric Monitoring - Variables - RX And, Z And, TT Ari, R CrB, CI Cyg, S Cyg, SS Cyg, U Her, BL Lac, SZ Lyn, DY Per, GK Per - SS Cyg (Time Series)
Attempts: Z And failed (wind), W And failed (abort due to cloud),
Astrometric Monitoring - Nearby Stars - Ross 248 (HH And), 61 Cyg, Groombridge 34, EV Lac, Teegardens Star
- Evening session (6.2 hrs duration).
Moderate conditions, wind affecting some images- Session operated under semi-automated control, with remote monitoring from indoors computer.
(Power-Line networking - no detectable drops outs in over 6 hours).- Ambient Temperature: -1.0 deg C (minimum)
No problems with dew at all during session - surprise !- CCD operation -30 degC (at 70% 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 deep sky objects -
