Observatories of the former Manfred von Ardenne research institute
The observatories of the former Manfred von Ardenne research institute are two observatories that were assigned to the former Manfred von Ardenne research institute . The older of the two ( “Manfred von Ardenne” observatory , built in 1956) is located in the Dresden district of Weißer Hirsch (Plattleite 27) and has been open to the public again since 2007. The younger of the two ( private observatory , built in 1969) is located near the von Ardenne family's private home in the Oberloschwitz district (Zeppelinstraße 7) and is not open to the public.
Observatory "Manfred von Ardenne"
General
After Manfred von Ardenne's return from the Soviet Union, Alexander Frantz created the observatory at Plattleite 27 (Lage) in 1956 for those who were very interested in astronomy . For its part, Ardenne made the building accessible to the public (at times referred to as the public observatory ). Inside the rotating dome, an artificial, fluorescent replica of the winter starry sky can be seen, so that guests can get an impression of the night sky when the sky is overcast or during the day.
Due to the need for renovation, the observatory was initially closed to the public in 1997, but on the occasion of the 100th birthday of Manfred von Ardenne after twelve months of reconstruction on November 20, 2007 again to the public (the dome holds approx. 20-25 people) in the evenings and made available for special events. Von Ardenne GmbH , on whose premises the observatory is located , bore the costs . It is supervised by teachers from the Martin-Andersen-Nexö-Gymnasium .
refractor
The Zeiss refractor with an objective diameter of 200 mm and a focal length of 3000 mm - built by Carl Zeiss in Jena between 1909 and 1911 - is a rarity among experts, as only six of these devices existed.
Main feature of the Ardenne refractor is, according to the supervisor a so-called E-mount lens as a classical Fraunhofer - achromatic to chromatic aberration correction with an aperture ratio of 1:15. As was common in the past, the refractor was automatically adjusted by a mechanical hourly drive until the refurbishment. The accuracy of these works was excellent and, in addition to visual observation, also made it possible to photograph the starry sky. The mechanical hour drive was replaced during the restoration in 2006/2007 by a control with the help of an electronic stepper motor .
Private observatory
Due to the light conditions in the building on the Plattleite, another spherical observatory, visible from afar, was built below Manfred von Ardenne's residential villa (Zeppelinstrasse 7 , location ). It is based on a steel construction on a reinforced concrete substructure according to plans by Johannes Bauer. Werner Bauch created the garden terrace surrounding the observatory . It is also equipped with a Zeiss refractor, but is not open to the public and is used as an amateur observatory.
