- Late evening  session (1.8 hrs), ended prematurely due to dew (dew shield accidently left off), plus indications of deteriorating sky conditions
- Session operated under semi-automated control, with remote monitoring from indoors computer. 
- Ambient Temperature:  7.5 deg C  (minimum)
- CCD operation -20 degC (at 66% average cooling).  
- main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis. and to test a trial version of RSpec software program under live conditions
