Location of the Bruno H. Bürgel Observatory in Berlin |
The Bruno H. Bürgel observatory is a public observatory in Berlin district Staaken of Spandau . It stands at 83 m above sea level. NHN height of the (new) Hahneberg ( 87.6 m ).
The observatory was founded by the non-profit amateur astronomical association Bruno-H.-Bürgel-Sternwarte e. V. established and operated by it. It is named after the Berlin astronomer and writer Bruno Hans Bürgel (1875–1948), who made a name for himself by spreading astronomical knowledge.
History and association
The Bruno-H.-Bürgel-Sternwarte e. V. was founded on April 6, 1982 as an amateur astronomical association. After monthly meetings and the publication of the magazine SPACE , the building permit for an observatory on the artificial Hahneberg on Heerstraße was enforced against nature conservationists in the Spandau district in 1988. Construction began in 1989 with funds from the German Lottery Foundation in Berlin . The observatory has a cellar and a solar power system. With the fall of the Berlin Wall , the Federal Border Guard building at the Staaken border control point on the West Berlin side and about 600 m north-northwest of the observatory became superfluous. It was transformed into a club house ( ⊙ ) and opened on April 4, 1992.
The association offers regular events such as public observations of the sky, astronomical lectures as well as workshops and occasionally excursions. Scientific lectures are offered in the club rooms on Fridays. The topics are astronomy, astrophysics , gravitational physics , satellite missions to the planets and other celestial bodies, impact events and meteorites , the universe in the most diverse radiation ranges from gamma to radio frequencies , extrasolar planets , black holes , sky surveys, comets , the earth as a planet with Plate tectonics , climate development, climate history, Mars robots, space travel and much more. The only adult education course in Berlin, “Introduction to Astronomy”, is offered at longer intervals .
telescope
On June 17, 2005 the inauguration of the 61 cm Cassegrain telescope, designed and built by the association, took place . The device has a focal length of 900 cm and is optimized for visual observation. It was developed and built by members of the association as a globally unique prototype and is today the most powerful reflector telescope in Berlin.
When the sky is clear, visitors have the opportunity to observe the moon, planets, nebulae or distant galaxies through the most powerful telescope in Berlin with a focal length of nine meters and a mirror diameter of 61 cm . The optical configuration of the telescope is unique in the world; the image in the main focus with Strehl 0.95 is unique for this size. Planets do not show any spikes (crosses of light, which can often be seen on high-resolution astronomical photos and also with bright objects in reflector telescopes of this type).
The Hahneberg is located on the extreme western outskirts of Berlin, it is the most favorable astronomical location in the capital. 5.0 mag faint stars can be seen visually with the naked eye.
