Session Notes

Uranus - Planet M1 - Supernova remnant (Crab Nebula) M36 - Open Cluster C/2014 A4 (Sonear) - Comet C/2013 X1 (PANSTARRS) - Comet     Photometric Monitoring - Variables   RX And, CY Lyr, DY Per, GK Per, WZ Sge     Astrometric Monitoring - Nearby Stars   None

- Late night session (1.5 hrs duration). Very clear skies. - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  temperature gradually falling from 6.0 degC to minimum of 3.0 degC (minimum) by end of session - CCD operation -20 degC (at 55% average cooling).  - Planned objectives of the session were to monitor selected variable stars and acquire images of selected gallery objects. - Observing session with Ian Shaw
