UIAS Observatory Open House

As of SPRING 2022, Public Open Houses are CANCELLED. We apologize for the inconvience, but we will have them up and running soon! Join the Guest Mailing List! to be notified!

Normally, every second Friday of the month we hold an observatory open house for anyone to attend. This is a great opportunity to see the night sky through our historic telescope. Read more below.
