Spring 2021 Stargazing Schedule
Stay tuned for virtual stargazing events!
Stargazing may also occur, weather permitting, after Friday Night Shows.
In the event of inclement weather (cloudy skies, temperature below 0° F), we will offer a 30 minute program in the Planetarium located on the first floor of the Physics Building Room 139.The extra credit opportunity for astronomy students is available regardless of the weather.
UWM Physics Building Skydeck (5th floor)
1900 E Kenwood Blvd
Milwaukee, WI, 53211
Take the elevator at the east end of the Physics building to the 4th floor and continue left to the staircase that leads to the roof. Unfortunately, the Skydeck is not wheelchair accessible.
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.
