Join us on the Skydeck at the UWM Physics building for free stargazing on select dates. Gaze through telescopes at the night sky and view the Moon, planets, star clusters, and other astronomical objects!

Due to COVID-19, our operations have changed. We are not holding in-person public events or stargazing; see our calendar for upcoming virtual events. We are also accepting private reservations.

About Our Telescope

Jupiter and Galilean moons

Thanks to a generous donation we received in 2018, we equipped our 14-inch Celestron telescope with a computerized mount permanently mounted on the Skydeck. The Paramount MX+ mount allows us to go to objects near and far with the push of a button. Once there, it will track the object as it moves across the sky throughout the night.
