- 11.6 hr overnight session, operated under automated control. Very frosty conditions. - CCD operation of -25 degC (at 62% average cooling). - main objective of the first half of the session was to acquire images for monitoring variable stars and a current comet in Auriga (C/2006 L1) - main objective of second half was to acquire a series of gallery shots of NGC galaxies in Canes Venatici and Ursa Major. - More Notes -
