Sherzer ObservatoryVance with 10" apo

The observatory is open on clear  Monday evenings following student Astronomy Club meetings that begin at 7:30pm in Room 402 Sherzer, and on CLEAR Tuesday evenings after 7:30pm from September through April (academic year), and at select times during spring/summer terms (May through August). The facility is operated by Physics & 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.

Fall 2018 Hours: A quick check of the observatory phone at 734.487.3033 may verify if we are observing on a particular evening. The observatory follows all University holidays and closures. For the most up-to-date information on events and open observing please check the Sherzer Observatory Facebook page.


The focal point of the observatory is the GEM mounted 10" f/14 apochromatic 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, and several computerized telescopes are used on our observation deck. In essence, students and staff have access to:


  • Celestron 14" Schmidt-Cassegrain on CGEM/DX GEM (at FLEEC Fish Lake, Lapeer, MI)
  • Celestron 9.25" and 8" NextStar GoTo Schmidt-Cassegrains
