- U Her (Mira variables)
- Aur KR, Cnc SY, CVn AM, CVn Y, RZ LMi, 
  SY Cnc, And Z, ER UMa, SU UMa, UX UMa (variables)
- NGC 4151, NGC 2782 (Seyfert galaxies)

- BL Lac (Blazar), 3C 273 (Quasar)
-Barnards Star, Gliese 412, Gliese 1245, Groombridge 34,
 Groombridge 1618, And HH (Nearby Stars)
- 6.3 hr session, cloud, some clear patches
- CCD operation of -20 degC (at 89% average cooling). .
- main objective was to acquire images of the Moon at 75% phase, followed by images selected stars for photometric analysis. In the event developing cloud meant that only images of the Moon were acquired before the observatory was closed.
