Bullet 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.
