Objects Session Notes
IC 5067 - Emission Nebula (Pelican Nebula) M97 - Planetary Nebula (Owl Nebula) M27 - Planetary Nebula (Dumbbell Nebula) Astrometric & Photometric Monitoring - U Gem (dwarf nova)
- HR Aur, KR Aur, SY Cnc, DY Per, GK Per (variables)
- Groombridge 1618, Groombridge 1830, Lalande 21185 (Nearby Stars)
- TBC
- Late Evening Session (4.6 hrs), - Operated under automated control / remote control. - Ambient Temperature 4.5 deg C, decreasing to 2 deg C, finally climbing to 1 deg as clouds developed. Poor seeing. - CCD operation -25 degC (at 66% 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 - -
