- Evening session (4.9 hrs duration).  
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature:  Temperature falling to minimum of 1 degC by end of session.
- CCD operation -30 degC (at 72% average cooling). 
- Main objectives of the session was to monitor selected variable stars & nearby stars and to take gallery images of a range of deep sky objects.

NGC 309 - Spiral Galaxy

NGC 309 (Cetus)
Galaxy is only just visible in this stacked image due to low S/N. This is a consequence
of significant sky background attributed to the Moon (Phase 63%, 29 arc deg offset) .
