  Attempts: Z And failed (wind),  S Cyg (wind)
Bullet Astrometric Monitoring - Nearby Stars
- DX Cnc, Teegardens Star
- Late Evening session (4.8 hrs duration). 
Good seeing
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
(Power-Line networking)
- Ambient Temperature: 0.5 deg C (minimum)
- CCD operation -30 degC (at 75% average cooling).  
- main objectives of the session were to perform further software testing and to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of deep sky objects. Opportunity taken to acquire a follow-up image of Comet ISON (C/2012 S1)
