Leopold-Figl-Observatorium, Observatory in Lower Austria, Austria

The Leopold-Figl-Observatorium is a branch of the Vienna University Observatory on the Mitterschöpfl, a secondary summit of the Schöpfl at 882 m, on the border between Altenmarkt an der Triesting and Klausen-Leopoldsdorf. Its main instrument is a Ritchey-Chrétien-Cassegrain telescope with a 1.5 m primary mirror and 12.5 m focal length, joined by a 60 cm reflector built by the Vienna observatory's workshop under Rudolf Pressberger.

The observatory was donated to the University of Vienna in 1965 by the province of Lower Austria for its 600th anniversary, on the initiative of governor Leopold Figl, who did not live to see it open. The foundation stone was laid on 13 September 1966 and the official opening took place on 25 September 1969.

The observatory is named after Leopold Figl, the Lower Austrian governor who pushed for its donation to the University of Vienna and died before its opening. It is open to visitors only on one annual open day, when the 1.5 m telescope and the 60 cm instrument built by Rudolf Pressberger's workshop can be seen.

The observatory stands at 882 m on the Mitterschöpfl, a secondary summit of the Schöpfl, on the border between Altenmarkt an der Triesting and Klausen-Leopoldsdorf, inside the core zone of the Wienerwald Biosphere Reserve. It opens to visitors only on one annual open day; there is no regular public access. The site was chosen for clean air, low light pollution and many clear, dry nights.

The 60 cm mirror telescope was built by staff of the University of Vienna observatory's own workshop under Rudolf Pressberger. Since 1996 images have been recorded digitally with OEFOSC, a spectrograph and camera allowing imaging, photometry and spectroscopy without changing instruments. The Coudé beam path was never built for financial reasons.
