- Evening session (6.5 hours)

Session operated under automated control with remote monitoring for most of the session.   User interventation after an bug continuing new plan and when it was elected to close the session due to cloud conditions and continuing rain shower risk.

- Main aim of the session was to acquire a selection of targets and to test new features in AstroMain /AstroShCap
