Magellanic Stream over Prague


From Vitkov hill, looking south. Suddenly realised that there's no need to worry about the vertical field of view of the camera since I'm replacing the sky entirely.

Think I have the calculation finally sussed : the Magellanic Clouds are at declinations ~ -70 degrees. The stream extends more-or-less 90 degrees due north, to declination ~+20 degrees. Since the lowest declination visible from Prague (latitude +50 degrees) is -40 degrees, the stream would span approximately 60 degrees across the sky. Or in other words it would be stupendous.
