- Night session (1.5 hours), excluding time spent focusing and testing /calibrating 'Cam1' Autoguiding.
- Main aims of the session were the testing new PHD2 messaging routines and acquisition of a selection of deep sky targets, together with some variable star, nearby star and comet targets (if conditions allowed)
- 12" LX200 + ST-10XME for imaging
- TS 80mm APO + ZWO ASI178MC for guiding & imaging
- Ambient Temperature: 3°C (min)
- CCD Temperature:  -20°C
