Barnards Star attempt (failed due to poor sky transparency)

 
- Evening  session (5.0 hrs). Sky transparency reducing significantly towards end of session. Dew formation about 2 hours into session
- Session operated under semi-automated control, with remote monitoring from indoors computer. 
- Ambient Temperature: -1.0 deg C  (minimum)
- CCD operation -25 degC (at 56% average cooling).  
- main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis. and to continue testing some new software routines
- autoguding controller
- spectral image focussing
