Objects Session Notes
Bullet IC 5067 / 5070 - Diffuse Nebula ("Pelican Nebula")
Bullet Astrometric & Photometric Monitoring
- SS Cyg  (dwarf nova)
- BL Lac (blazar)
 - GP And, RX And, EV Lac, RU Peg, GK Per (variables)
- Barnards Star, 61 Cyg Ross 248 (HH And), Groombridge 34

Time Series
- EV Lac (run spoiled by developing cloud)

KR Aur, U Gem, FU Ori attempts failed (cloud)
Lalande 21185, Gliese 412 attempts failed (cloud)
- All night session (8.6 hrs), operated under automated control. Cloud developed after 4.5 hrs.
- Ambient Temperature 1.0 degC (minimum), climbed to 6.0 degC by end of session as cloud developed.
- CCD operation of -20 degC 
(at 59% average cooling).  
- main objective of the session was  to acquire images of key selected stars for ongoing photometric and astrometric analysis. 
- a secondary objective, to test revised routine for automated guiding between frames, was not possible due to early termination of the session.
