About Hans-Haffner-Sternwarte
The observatory was built in 2009 and inaugurated on 18 December 2009, during the International Year of Astronomy. It is named after Hans Haffner (1912-1977), an astronomer from Würzburg. It is operated by the Naturwissenschaftliches Labor für Schüler at the Friedrich-König-Gymnasium in cooperation with the University of Würzburg's Chair of Astronomy, and has been an officially recognised school and university observatory since 2016.
Telescopes & research
The main instrument is a 50-centimetre Planwave astrograph on a 10-Micron GM4000 mount, which saw first light on 21 March 2012. In 2015 the site was extended with a 3-metre radio telescope, inaugurated on 4 October 2017. Students and pupils take part in visual observations, astrophotography, and scientific research at the observatory as part of its educational mission.
