Objects Session Notes
Pluto M3 - Globular Cluster M4 - Globular Cluster M9 - Globular Cluster M16 - Nebula (Eagle Nebula) M23 - Open Cluster NGC 6342 - Globular Cluster NGC 6356 - Globular Cluster NGC 6369 - Planetary Nebula (Little Ghost Nebula) Photometric Monitoring - Variables - Z And, R CrB, AM CVn, CI Cyg, SS Cyg,
- SS Her, U Her, BL Lac, RZ LMi
- FG Sge, WZ SgePhotometric Monitoring - Nearby Stars - 61 Cyg, EV Lac, Barnards Star
- Late Evening Session (3.3 hrs), - Operated under automated control - Ambient Temperature 6.5 deg C, decreasing to 4 deg C. - CCD operation -25 degC (at 70% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire images of certain gallery objects including several declination objects lying only 5-12 deg above the horizon. - - [Attempt at session on 2009-05-22, but aborted after 40 minutes due to poor seeing and developing cloud]
