I was actually shooting a touristic building under starry sky just in the opposed direction and the suddenly came to the idea to turn around the camera.
I was quite surprise by having the milky way just in the back. The light pollution at the silhouettes came from the sun rising below horizon (04:30) .
I had waited so long to get rid of the the already very full moon that gave me a starshoot window of about 3/4 hour.
Since that moment i´m planning to come back at new moon to take the capture Mrs. Milky deserves :)
