Further Events

More Astronomy lectures are planned for 2025. Dates and topics are in preparation, but the scheduling has not yet been finalised.

Guided Tours

Public tours take place on the first and third Wednesday of every month, regardless of the weather. Reservations are not required, but we would still ask you to register using the contact form so that we can plan the tours better. If the weather is favorable, we will of course also make observations of the sky with the observatory's instruments.
