Time Series
- EV Lac, Vesta
- Lalande 21185 attempt (dawn)
- All night session (10.3 hrs), operated under automated control. Windy. - Ambient Temperature 1.0 degC (minimum),
Temperature climbing to 4 degC by dawn.- CCD operation of -20 degC
(at 58% average cooling).- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - secondary objective was to test revised routines for automated guiding between frames
