- HR Aur, KR Aur, RZ LMi (variables)
- Late Evening/Night Session (5.7 hrs), - Operated under automated control / remote control. - Ambient Temperature 7 deg C, decreasing to 6 deg C by end of session. Relatively poor seeing - CCD operation -25 degC (at 75% average cooling). - secondary objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - attempted TPoint Mapping Run at end of session (but unable to complete before dawn). - - Notes from 2009-04-30
