The night sky in Tautenburg is so dark that the Milky Way is easily visible. I don’t have the best camera, so the observatory’s night assistant made some jokes about how he could shoot the Andromeda galaxy lazily while walking with his Canon EOS 5D Mark II and a good telephoto lens.
This picture is already the average of three independent photographs to minimize the noise. That’s why one of the planes apparently turns off all its lights for a while. I also subtracted a dark flat field from each frame, just like the real astronomers ;-)
The assistant just opened the dome. The clouds had disappeared just in time for the night. During the actual observation, the lights will be turned off as well to get as much contrast as possible for the objects in the sky.
Don’t forget a flash light!
