MDM Observatory
The MDM Observatory is an optical astronomical observatory on Kitt Peak (west of Tucson, Arizona, USA), adjacent to Kitt Peak National Observatory. It is owned and operated by the University of Michigan, Dartmouth College, Ohio State University, Columbia University, and Ohio University. The "MDM" acronym stands for Michigan-Dartmouth-MIT, because the Massachusetts Institute of Technology was part of the operating consortium in the past.
It has two reflecting telescopes, the 2.4 m Hiltner Telescope (since 1986), used for galactic surveys, and the 1.3 m McGraw-Hill Telescope (since 1975), which was originally located near Ann Arbor, Michigan.〔

The mirror of the 2.4 m Hiltner Telescope is aluminum coated Cer-Vit, and usable foci include f/7.5 and f/13.5 Cassegrain foci. 〔 http://www.astro.lsa.umich.edu/obs/mdm/technical/hiltner.html 〕 The telescope was built in 1986 and the mirrors were re-polished in 1991.〔http://www.site.uottawa.ca:4321/astronomy/HiltnerTelescope.html〕 It was named after astronomer W. Albert Hiltner (1914-1991).〔http://bentley.umich.edu/observatory/history/directors/hiltner.php〕
