Session Notes

Jones 1 - Planetary Nebula (PK 104-29.1)     NGC 1528 - Open Cluster (Herschel VII-61)   Photometric Monitoring - Variables - RX And, U And, W And, Z And, R CrB, CI Cyg, S Cyg, SS Cyg, U Her, BL Lac, DY Per, GK Per, FG Sge, U Sge, V Sge     Astrometric Monitoring - Nearby Stars - None

- Evening session (3.1 hrs duration).  Moderate conditions - Session operated under semi-automated control, with remote monitoring from indoors computer.   Second use of Power-Line networking (regular dropout of connection at 4 min 5sec intervals, reason unknown but resolved by setting Auto Reconnect On in the VNC viewer)  - Ambient Temperature: 3.5°C (minimum)  Dew requiring corrector plate to be cleared with hair dyer on 2-3 occasions. - CCD operation -25°C (at 69% average cooling).   - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of planetary nebula  -
