Session Notes

Hickson 23 - Galaxy Group (NGC 1214 et al) Hickson 30 - Galaxy Group (PGC 15620 et al) Hickson 41 - Galaxy Group (PGC 28764 et al) Hickson 66 - Galaxy Cluster (PGC 48226 et al) Hickson 94 - Galaxy Cluster (NGC 7578 et al, ARP 170)     M33 - Spiral Galaxy     NGC 5676 - Spiral Galaxy (Herschel I-189)     Photometric Monitoring - Variables     - SS Cyg,  BL Lac, DY Per, GK Per, FG Sge, SU Tau     Astrometric Monitoring - Nearby Stars   - None

- Night Session (7.2 hours duration). Cloud interrupted the session on several occasions - Main aim of the session was to acquire images of a selection of variable stars, nearby stars and deep sky targets. Secondary aims were to test recent software fixes & modifications of the Observatory Control Program (CCDApp2). - Fully Automated operation  (First part of the Session was monitored remotely from indoors to observe operations and spot any new or recurrent issues before retiring to bed whilst the session continued unattended until dawn.  ) - - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding - Ambient Temperature:  7°C (minimum) - CCD Temperature:  -15°C (82% av. power) - Notes from 2018-09-04 >>
