DF9CY Christoph Petermann - Astrophotography

I got alarmed by amateur radio activity. The sky was almost clear but no where it should have been clear. Nevertheless I managed to take some good shots.

The same happened two days later. Indeed there were five days with a visual aurora in a row - but I am not always at home.
