Description

What a terrible night, when I loaded the car the sky was clear and when I arrived at the oberservation site the first clouds appear. When the gear was completly set up, the whole sky was hidden behind clouds. This image is the result of a few small cloud gaps, some of them lasts only a few minutes.
