Star Spectra - Planetary Nebula SAO 49491 - Wolf Rayet Star (WR 140) M57 - Planetary Nebula NGC 6572 - Planetary Nebula ("Emerald Nebula") NGC 6826 - Planetary Nebula ("Blinking Planetary") NGC 7662 - Planetary Nebula ("Blue Snowball") Astrometric & Photometric Monitoring - SS Cyg, U Gem (dwarf nova)
- SS Her (mira variable)
- BL Lac (blazar)
- KR Aur, SY Cnc, AM Her, SZ Her, RZ LMi, TZ Lyr (variables)
- V2491 Cyg (nova)
- Ross 248, Barnard's Star, 61 Cyg, Gliese 1245, Groombridge 34 (Nearby Stars)
- All night session (7.2hr) - CCD operation of -20 degC
(at 64% average cooling).- main objective to try out acquisition of stellar spectra using recently purchased Star Analyser 100. - secondary objective was to acquire images of certain selected stars for ongoing photometric and astrometric analysis - opportunity was also taken to acquire images of selected planetary nebula, including acquisition of nebula spectra using Star Analyser 100.
