Session Notes

EV Lac - Nearby Star (GJ 873, 16.5 ly)     Hickson 80 - Galaxy Cluster (PGC 56588 et al) Hickson 88 - Galaxy Cluster (NGC 6977 et al) Hickson 94 - Galaxy Cluster (NGC 7578 et al, ARP 170)     Photometric Monitoring - Variables     - None    (TT ARI attempt failed due to cloud)     Astrometric Monitoring - Nearby Stars     - EV Lac

- Late Night Session (1.1 hrs duration). Initially clear , but clouds rolled in after 1 hour - Session conducted as a Fully Automated Run. (Session was monitored remotely in order to observe target centering which had been problematic in last session and look out for any further instances of Error 203 problem or blue screen crashes that had affected the last session badly). - Main aim of the session was to confirm that target centering was working and wasn't affected by the issue that had caused problems during the last session (S618). Secondary aims were to acquire images of a selection of deep sky, variable star & nearby star targets and perform a further test of fully automated observatory operations. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding - Ambient Temperature:  9°C (minimum) - CCD Temperature:  -15°C (78% av. power) - Notes from 2018-08-19 >>
