The Kuffner observatory is one of two telescope-equipped public astronomical observatories situated in Austria's capital, Vienna. It is situated in the West of the city's Ottakring district, on the slope of the Gallitzinberg at 302 m altitude. Originally a private research institution, it was converted into an educational astronomy facility after World War II as buildings and city lights had encroached to a degree that severely hampered scientific nightsky observations. Today the main tasks of the observatory consist in public education on astronomy, operating and preserving the historical equipment, and minor projects in scientific astronomy.
The observatory was noted for its work on photometry, conducted by astronomer Karl Schwarzschild, star catalogs, and the determining of distances to other stars.[1] The observatory has several astronomical instruments of historical interest, including a noted heliometer and large meridian circle, and also a vertical circle.[1]
The observatory's first observations were made in 1886.[1]
