Sherzer ObservatoryVance with 10" apo

The observatory in general is open on clear Tuesday evenings that begin at 7:40 p.m.—after lab classes end— from September through April (academic year), and at select times during spring/summer terms (May through August). Note the current times below. 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.

Fall 2019 Hours: A quick check of the observatory phone at 734.487.3033 may verify if we are observing on a particular evening, if we are not too busy to answer!  We plan to have the observatory open primarily for lab student observations but the public is always welcome. Beginning September 10 through mid-November we have set aside CLEAR Tuesday evenings 8-10pm DST to enjoy views of the moon and autumn stars! Other select evenings may find the door open except Wednesday evenings- that is reserved for ASTR 315 class ONLY. 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.


A great experience under the stars at EMU's Fish Lake Environmental Center featuring the 29-inch "Dobfather" telescope and some of the instruments listed below. Additional registration information for our next trek will be posted here by mid-January 2020.


The focal point of the observatory is the computer guided GEM mounted 10" 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 are used on our observation deck. In essence, students and staff have access to:


  • Celestron 14" Schmidt-Cassegrain (C14) on CGEM/DX GEM (at FLEEC Fish Lake, Lapeer, MI)
  • Celestron 9.25" and 8" NextStar GoTo Schmidt-Cassegrains
  • Orion 16" SkyQuest XX16 GoTo Truss Dobsonian (at FLEEC Fish Lake)
  • Two Orion 12" SkyQuest GoTo Newtonians
  • Several 8" and 10" Newtonians on Dobsonian mounts
  • Lunt 60mm .7A  Model LS60T solar H-alpha telescope
  • Coronado H-alpha and CaK solar scopes (at FLEEC Fish Lake)
  • Historically registered 4" Alvan Clark refractor circa 1878
  • 10" & 12.5" Newtonian telescopes (at FLEEC Fish Lake)
