- Night Session (5.1 hours)

Session operated under automated control
Session preceeded by PHD2 testing/tuning

- Main aim of the session was to test a number of new program features and to acquire images of a selection of targets
   
- 12" LX200 + ST-10XME for imaging
- TS 80mm APO + ZWO ASI178MC for guiding & imaging
- Ambient Temperature:  3°C (min)
(Dew heaters on new automated control)
- CCD Temperature:  -20°C  (67% av. power)
