- Barnard's Star (Nearby Stars)

- WZ Sge attempt (failed due to poor sky conditions)


- Evening session  (6.9 hrs), operated largely under automated control with remote monitoring.
- Ambient Temperature 2 - 3 degC dropping to 0.5 degC (minimum), then rising to 2 degC 
- CCD operation of -20 degC 
(at 57% 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 mosoic of two messier open clusters M29 & M34
