The WIYN 0.9-meter Telescope

The Kitt Peak National Observatory is located on Kitt Peak of the Quinlan Mountains in the Arizona-Sonoran Desert on the Tohono O'odham Nation. With over twenty optical and two radio telescopes, it is one of the largest gatherings of astronomical instruments in the northern hemisphere.

The Wisconsin-Indiana-Yale-NOAO (WIYN) Observatory is situated atop Kitt Peak National Observatory. It is owned and operated by the WIYN Consortium, which consists of the University of Wisconsin, Indiana University, National Optical Astronomy Observatory (NOAO), the University of Missouri and Purdue University. This partnership between public and private universities and NOAO was the first of its kind. In 2001 the WIYN Consortium, led by the University of Wisconsin-Madison and Indiana University, assumed operational responsibility for the historic 0.9-meter (36-inch) telescope at the National Science Foundation's Kitt Peak National Observatory.
