This page is designed to be a local information point for users (and potential users) of the ARC 3.5m Telescope at the University of Chicago. For a more extensive discussion of all the telescopes at Apache Point Observatory (APO), which includes the 3.5m and the SDSS 2.5m, check out the APO website.
