Join us for our yearly Messier Marathon open house on Friday, March 13 from 8pm – 10pm! We’re thrilled to once again partner with the Milwaukee Astronomical Society, where they’ll provide an educational presentation about Messier objects and marathons, hands-on educational activities, and Messier observing outside on the South lawn if clear. We’ll also have engaging family activities, a scavenger hunt and prizes, and more for your family to enjoy. 

The open house will take place rain or shine. This does not include use of telescopes within the building. Reservations are required, and tickets must be purchased in advance. This year, parking will be on-site at the observatory. Guests driving and parking at the observatory must purchase tickets prior to the event.
