Crescents in December 2012

Version 16.12.2012 Martin Elsaesser,

Young crescent on 14. December

The weather was bad in the afternoon with layers of high cirrus clouds causing white skies and even thicker clouds were approaching from the west. As there would be no chance to observe after sunset i had to use the imaging-system to punch through the clouds in daytime. This it did easily enough, as the crescent was already quite wide at 16° elongation.
