Explore the heavens during one of our astronomy nights. Open houses involve presentations on a range of fascinating astronomical phenomena, instruction on the telescopes, and, when weather permits, observing with our beautiful historic Fitz telescope as well as modern supplemental telescopes.

Please note: astronomy events at the Observatory take place even if the weather does not permit observing. We offer unique tour and telescope demos when we can't observe the night sky. Tickets are required, and open house registrations are capped at 100 guests. You can arrive anytime from 8:30 pm to 10 pm. You will be given a time slot for visiting the dome. While you are waiting, check out other features and presentations.
