The W. M. Keck Observatory is an astronomical observatory with two telescopes at an elevation of 4,145 meters (13,600 ft) near the summit of Mauna Kea in the U.S. state of Hawaii. Both telescopes have 10 m (33 ft) aperture primary mirrors, and, when completed in 1993 (Keck I) and 1996 (Keck II), they were the largest optical reflecting ...
A rough jeep trail was built in 1964 under Governor John A. Burns, and a small telescope determined that Mauna Kea would be an ideal place for an astronomical observatory. The Hale Pōhaku area was used as a construction camp for the building of the observatories through the 1970s, and the road realigned in 1975.
W. M. Keck Observatory at dawn, Mauna Kea, Hawaii The Keck II telescope on Mauna Kea, Hawaii projects a laser beam into the night sky to form an artificial guide star for adaptive optics. The galactic plane of the Milky Way is visible in the sky to the right of the image. The stars are trailed in this 3 minute fixed camera exposure due to the ...

The Canada–France–Hawaii Telescope (CFHT) is located near the summit of Mauna Kea mountain on Hawaii's Big Island at an altitude of 4,204 meters (13,793 feet), part of the Mauna Kea Observatory. Operational since 1979, [ 1 ] the telescope is a Prime Focus/ Cassegrain configuration with a usable aperture diameter of 3.58 metres (11.7 ft).
The Ohana project aims to use seven big telescopes on top of Mauna Kea, Hawaiʻi Big Island, in an interferometer configuration. Mauna Kea is a former volcano whose height is 13,600 ft (4,145 m). It is a good site for telescopes which probe the universe in the optical and infrared wavelengths because of its altitude and low levels of light ...
