A quick photosession

At last out in the dark again. I did a quick photosession by the lake Erken, still frozen even though the spring is around the corner. When I arrived I notices a faint Aurora Borealis low in the north. The Milkyway in Cygnus seems to dive in the lights. Later on I met this beautiful old oak with parts of it

unfortenaly below on the ground. to the left of the oak you see planet Jupiter.
