Objects Session Notes
Altair - star SZ Her - Eclipsing Binary 93P/Lovas - Comet C/2006 OF2 (Broughton) - Comet NGC 7727 - Spiral Galaxy NGC 7585 - Spiral Galaxy Vulpecula - Constellation (incl M27 & The Coat Hanger) Astrometric & Photometric Monitoring
- SS Cyg (Dwarf Nova)
- BL Lac (Blazar)
- U Her, W And, U And (Mira variables)
- SZ Her, CY Lyr, TZ Lyr (Variable)
- Barnard's Star, Ross 248 (And HH) Groombridge 34, Gliese 1245, HIP 3829, Teegarden's Star (Nearby Stars)
- Session (4.7 hour duration), reasonably clear all night. - CCD operation of -15 degC (at 62% average cooling). - main objectives were to acquire images of selected variable stars and nearby stars for ongoing photometry and astrometry - opportunity was taken to acquire images of galaxies ARP 222 & 223 and a few faint comets (including 93P/Lovas) -
