- Evening Session (2 hrs duration).
Clear skies, low wind.
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Main aims of the session were to acquire images of selected deep sky objects and to test updated routines for initiating PHD2 Guiding from my CCDApp2 Observatory Control Software. The session also aimed to continue testing of dual camera operations using both PHD2 and SharpCap 3.0.

- 12" LX200 + ST-10XME for imaging
- TS 80mm APO + ZWO ASI178MC for guiding & imaging
- Ambient Temperature:  0 degC (minimum)

C/2017 T1 (Heinze) - Comet

Attempted observation of comet C/2017 T1 (Heinze), but the orbital elements that I was using were out of date, which meant that the imaged star field (below) was 1 deg 35 min away from the correct position of the comet

C/2017 T1 (Heinze) - attempt
(Camelopardalis, Sun distance 1.17 AU)
(Comet lies 1 deg 35 min away due to the use of invalid/out-of-date orbital elements)
This was considerably more than the 3 arc minute error just 3 weeks earlier)
