UH 2.2m Telescope

The University of Hawai'i 88-inch telescope—called UH88, UH2.2, or simply 88 by members of the local astronomical community—is situated at the Mauna Kea Observatories and operated by the University's Institute for Astronomy. It was constructed in 1968, and entered service in 1970, at which point it was known as "The Mauna Kea Observatory". It became one of the first professional telescopes to be controlled by a computer. The telescope was built with funding from NASA, to support Solar System missions, and is controlled by the University of Hawai'i. The success of the telescope helped demonstrate the value of Mauna Kea for astronomical observations.On December 4, 1984 it became the first telescope to make optical closure phase measurements on an astronomical source using an aperture mask.

UH88 is a Cassegrain reflector tube telescope with an f/10 focal ratio, supported by a large open fork equatorial mount.
