Objects Session Notes
NGC 7293 - Planetary Nebula (Caldwell 63, Helix Nebula) NGC 7479 - Spiral Galaxy, with SN2009jf (Caldwell 44) C/2006 W3 (Christensen) - Comet Photometric Monitoring - Variables - RX And, U And, W And, Z And, TT Ari,

Astrometric Monitoring - Nearby Stars - Barnards Star, 61 Cyg, Groombridge 34
- EV Lac,
- Session in two parts:
A : Early evening session (0.6 hr), cut short by windy conditions
B: Evening session . Sufficient wind to necessitate removal of dew shield to obtain suitable image quality. Early images discarded due to wind shake/star blurring.- Operated under semi-automated control with remote monitoring - Ambient Temperature 2 deg C (minimum) - CCD operation -20 degC (at 51% average cooling). - Main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. Opportunity taken to acquire follow-up images of dwarf planet Eris.
