About this observatory

Wiesbaden Observatory occupies the rooftop of the Martin-Niemöller-Schule in Wiesbaden, Germany, where the volunteers of the Astronomische Gesellschaft Urania have been sharing the night sky with the public since the 1920s.

About Wiesbaden Observatory

The observatory is run by the Astronomische Gesellschaft Urania e.V. Wiesbaden, an amateur astronomy association, and sits at an elevation of 190 metres on Bierstadter Straße in the city.

History

Wiesbaden Observatory was founded in November 1925 by the astronomer Franz Kaiser, who discovered 21 asteroids during his career, together with a group of fellow amateur astronomers. The original observatory was destroyed during the Second World War and rebuilt in 1954, before the society moved to its current rooftop location in 1974.

Telescopes & research

The observatory's instruments include an apochromatic refractor of 1600/206mm, a secondary 1800/120mm refractor, a portable 600/110mm refractor, a 1270/250mm Dobsonian reflector, large 2×125mm binoculars, and a 4800/300mm Maksutov reflector, along with solar filters and cameras for astrophotography and solar observation.

Location & getting there

The observatory sits on the roof of the Martin-Niemöller-Schule at Bierstadter Straße 47 in Wiesbaden, western Germany, at an elevation of around 190 metres — an accessible, independently reachable public location within the city itself.
