The open observation nights/days are held when weather and other factors allow. Check our calendar to find out when the next observation night is held.
During these events we use the Observatory’s main telescope, a Carl Zeiss Refractor from 1911. If there are many visitors we can also bring out the more current amateur telescopes. Since the light of the city makes observing difficult, we mostly observe the Moon and the planets. For solar observation we use a spacial telescope or a filter to make it safe to look at the Sun.
Public observation nights have been held since the 19th century. They have always been available to visitors if arranged in advance. The last few decades have seen the appearance of regular observing.
Observation nights are free for all.
