- Late evening  session (1.7 hrs), ended when cloud cover came over.
- Session operated under semi-automated control, with remote monitoring from indoors computer. 
- Ambient Temperature:  7 deg C  (minimum)
- CCD operation -20 degC (at 65% average cooling).  
- main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis, and to attempt acquisition of Planetary Nebula Jones 1.
- Sets of flats taken on 2010-08-28 under the same session id.
