Objects Session Notes
UGC 12846 - Spiral Galaxy with Supernova 2007od 17P/Holmes - Comet NGC 7635 - "Bubble Nebula" Sharpless 2-155 - Emission Nebula, "Cave Nebula" Dwarf Planet, 1 Ceres M46 - Open Cluster NGC 2438 - Planetary Nebula M47 - Open Cluster Astrometric & Photometric Monitoring
- SS Cyg (dwarf nova)
- BL Lac (Blazar)
- S Cyg (mira variable)
- Z And, TT Ari (variables)
- Evening session (4.6hr), operated under automated control for majority of session. CCD operation of -25 degC (at 74% average cooling). - main objective of the session was to acquire an image mosaic of comet 17P/Holmes (now grown to larger than the apparent diameter of the moon) -secondary objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis -opportunity was also taken to acquire gallery images of Caldwell 51 (IC 1613), and certain other comets and deep sky objects.
