DescriptionOskar Lühning Telescope 01.jpg |
English: Oskar Lühning Telescope, a Ritchey–Chrétien telescope at the Hamburg Observatory. With an aperture of 1.2 m and a focal length of 15.6 m, it is the observatory's largest telescope and indeed one of the largest in all of Germany. It is also the observatory's youngest telescope, having been built in 1975; however, the mount and the dome building date from 1954.
