All-sky photo of the night sky (annotated)

This is a medium resolution annotated version of the largest open-source, freely available all-sky photo of the night sky. The colossal sky-scape was compiled using images taken by astrophotographer Eckhard Slawik from the best and darkest locations around the globe: Germany (Waldenburg), Spain (Tenerife, La Palma), Namibia and Chile. A non-annotated high-res version can be found here.
