Objects Session Notes
C/2007 N3 (Lulin) - Comet NGC 6543 - Planetary Nebula (Caldwell 6, "Cats Eye Nebula", H IV-37) NGC 6552 - Spiral Galaxy C/2009 F6 (Yi-SWAN) - Comet NGC 2403 - Spiral Galaxy (Caldwell 7) IC 342 - Spiral Galaxy (Caldwell 5) NGC 4236 - Spiral Galaxy (Caldwell 3) Moon R Leo - Star Astrometric & Photometric Monitoring - SS Cyg (dwarf nova)
- CI Cyg (mira variables)}
- attempts at BL Lac, S Cyg (failed - poor sky transparency/cloud)
- Late Evening Session (3.2 hrs), - Operated under automated control / remote control - Ambient Temperature 1 deg C, then rising to 3 deg C
Thin cloud blocking Southern Sky, cloud developing by dawn
Full Moon- CCD operation -25 degC (at 66% average cooling). - main objective of the session was to collect images of gallery objects (mainly Caldwell objectives) that were not easily acquired using previous 8" LX200 - secondary objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire images of Comet C/2009 F6 (Yi-SWAN) - -
