The observatory in general has been open on clear Monday evenings at 7:30pm October through April (academic year), and at select times after sunset during spring/summer terms (May through August).  The facility is operated by Physics and Astronomy staff and student volunteers from the EMU Astronomy Club. Additionally, observing sessions are performed by students in several of the astronomy courses on clear nights during the semester.

Spring/Summer 2024 Hours: The observatory will open on select CLEAR evenings following the student astronomy club meetings which typically have taken place at 8:30pm on alternate Mondays in 402 Sherzer, specific dates TBA as soon as possible.  For the most up-to-date information on events and open observing please check the Astronomy Club page for details.


The focal point of the observatory is the computer guided GEM mounted 10-inch  f/14 apochromatic (triple lens) refractor with a 4" apochromatic refractor guide scope that is housed in the main dome. A secondary dome contains an automated Celestron EdgeHD 9.25" SCT for digital imaging from a control station located below in 404 Sherzer, and several computerized telescopes that are used on our campus observation deck. Even larger aperture instruments are kept at EMU's Fish Lake Environmental Center near Lapeer, MI, under darker skies. In essence, students and staff have access to:
