A working radio telescope can be seen at the south end of the Museum island at the open-air exhibition ground. This original instrument from the pioneering period of radio astronomy was used in the Netherlands after 1945 for solar research. In the concrete foundations for the parallax mounting, there is a small observation room containing the receiving devices. Radio-astronomical observations are carried out by the Observers Group , Deutsches Museum Observatory, as part of their program of events. At regular intervals, the group also offers guided tours of the radio telescope.
Observation results Several radio sources have now been identified using the telescope.
