Bruno-H.-Bürgel-Sternwarte, Public observatory in Staaken, Berlin, Germany

Bruno-H.-Bürgel Observatory is a public observatory in Berlin's Staaken district, located on Hahneberg hill at approximately 83 meters above sea level. The facility includes an auditorium, library, exhibition gallery, and telescope observation workshop.

The Bruno-H.-Bürgel-Sternwarte e.V. association was founded on 6 April 1982, and construction of the observatory on the artificial Hahneberg began in 1989 with funds from the Stiftung Deutsche Klassenlotterie Berlin. After the Wall fell, the redundant Federal Border Guard building at the Staaken checkpoint, about 600 m north-northwest, was converted into the clubhouse and opened on 4 April 1992.

The observatory is named after Bruno Hans Bürgel (1875–1948), a Berlin astronomer and writer honoured for spreading astronomical knowledge among the public. The association founded on 6 April 1982 runs it, and on Fridays its rooms host scientific lectures on topics from black holes and exoplanets to Mars rovers and spaceflight. At longer intervals it also holds Berlin's only Volkshochschule course, "Introduction to Astronomy".

The observatory stands on the artificial Hahneberg hill at the western edge of Berlin, about 600 metres south-southeast of the former Staaken border checkpoint. Its dark surroundings make it Berlin's most favourable astronomical site: stars down to magnitude 5.0 are visible to the naked eye. Public sky observations depend on clear weather.

The facility houses Berlin's largest telescope, a 61-centimeter Cassegrain instrument specially calibrated for visual observations installed in 2005. Amateur stargazers appreciate this instrument for its precision and clarity when viewing distant objects.
