Sherzer ObservatoryVance with 10" apo

The observatory is open on clear  Tuesday evenings from September through April (academic year) following Astronomy Club meetings, and at select times during spring/summer terms (May through August).  It 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.

We are also scheduled to open on CLEAR Monday evenings after 7:30pm (and perhaps occasional Thursday evenings later in the term) for the Fall 2017 term for lab observations. A quick check of the observatory phone at 734-487-3033 may verify if we are observing on a particular evening. The observatory observes all university holidays and closures.

Sorry, we have no eclipse glasses remaining and expect no more for the big day. The observatory will not be open on Monday, Aug 21 as the primary staff and some volunteer students will be far away in the path of TOTALITY! This will leave too few folks here to effectively open the facility to manage any large gathering and safely observe only a partial eclipse. We want them to see TOTALITY!  For many this will be their first experience at seeing a total eclipse, thus the departure to points along that 70 mile wide path from Oregon to South Carolina.  If you are also not in the path, then exercise caution by not overriding common sense in staring at the brilliant disk of the partially eclipsed Sun even for short periods of time.  Do some planning and your homework by finding information on the Internet.  One such site is the NASA Eclipse page. 


The focal point of the observatory is the 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 including a large Celestron 14-inch go-to telescope are found on our observation deck. In essence,  students and staff have access to:


  • Celestron 14" Schmidt-Cassegrain on CGEM/DX GEM
  • Celestron 9.25" and 8" NextStar Schmidt-Cassegrains
  • Orion 16" SkyQuest XX16 GoTo Truss Dobsonian (at KEEC Fish Lake)
  • Two Orion 12" SkyQuest GoTo Newtonians
  • Several 8" and 10" Newtonians on Dobsonian mounts
  • Lunt 60mm .7A solar H-alpha telescope
  • Coronado H-alpha and CaK solar scopes
  • Historically registered 4" Alvan Clark refractor
  • 10" & 12.5" Newtonian telescopes (at KEEC Fish Lake, Lapeer, MI)
Analysis equipment
  • Canon 60Da DSLR
  • Canon 20Da DSLR
  • Canon XSi DSLR
  • Canon TSi DSLR
  • ZWO all-sky/astro CCD
  • Orion StarShoot color CCD
  • Celestron NightWatch color CCD
  • Stellacam II CCD video camera
  • SSP-5 PMT Photometer
  • RSpec-Explorer spectroscopic telescope system
  • Daystar .6A & .7A H-alpha filters for 10-inch apo and 8" SCT's
  • Lunt 60mm .7 A H-alpha telescope
