- S Cyg, SS Her, U Her (mira)
- HR Aur, SY Cnc, R CrB, AM CVn, CI Cyg, RZ LMi, CY Lyr, DY Per, AN Ser, FG Sge, U Sge, V Sge, WZ Sge, ER UMa (variables)
- Gliese 1245 (V1581 Cyg) (Nearby Stars)
- SS Cyg attempt (failed due to cloud)
- Late Evening Session (5.4 hrs), - Operated under automated control - Ambient Temperature 6 deg C, decreasing to -0.5 deg C by end of session - CCD operation -25 degC (at 63% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire images of certain gallery objects including two low declination objects (M68 and M83) lying only 3-5 deg above the horizon. - -
