Bullet Saturn
Bullet M95  - Spiral Galaxy
Bullet UGC 5378 - Spiral Galaxy with Supernova 2007S
Bullet Astrometric & Photometric Monitoring
- SS Cyg, U Gem, (dwarf novae)
- HIP 4429 (suspected variable)
- U And, W And (Mira variables)
- Z And, DV UMa  (variables)
- BL Lac (BL Lac blazer)
- HH And, Groombridge 34 (Nearby Stars)

- 3.8 hr session cut short by deteriorating sky conditions
- CCD operation of -25 degC (at 69% average cooling). .
- the other main objective was to acquire images for photometric monitoring of the variables stars U And, W And, SS Cyg and a suspected variable HIP 4429.
- opportunity was taken to acquire some exploratory images of U Gem, RZ LMi and DV UMa which may be added to future variable star monitoring.
