Objects Session Notes
NGC 7461 - Spiral Galaxy with Supernova 2007hj M1 - Supernovae Remnant NGC 1555 (Hind's Variable Nebula) Polar Alignment Astrometric & Photometric Monitoring
- SS Cyg (Dwarf Nova)
- BL Lac (Blazar)
- U And, W And, U Her (Mira variables)
- Z And, SZ Her (Variable)
- Session duration 3.6 hr, interrupted by cloud during first hour, becoming very clear later. - CCD operation of -20 degC (at 77% average cooling). . - main objectives were to acquire images of selected variable stars for ongoing photometry, to check out new software routines and refine polar alignment. - opportunity was taken to acquire follow up images of Supernova 2007hj in NGC 7461 and images of M1 and Hind's Variable Nebula (T Taurii) - More Notes (Polar Alignment) -
