Mauna Kea

Mauna Kea is a volcano on the island of Hawaii. Standing 13,803 ft above sea level, its peak is the highest point in the U.S. state of Hawaii. However, much of Mauna Kea is below sea level; when measured from its oceanic base, its height is {{#invoke:Math|precision_format| 33,464.566929134 | -2}} ft (10,200 m)—more than twice Mount Everest's base-to-peak height of 3,650 to 4,650 metres (to ft).

Gemini North

Canada–France–Hawaii Telescope

The Canada–France–Hawaii Telescope is located near the summit of Mauna Kea mountain on Hawaii's Big Island at an altitude of 4,204 meters (13,793 feet), and is one of the observatories that comprise the Mauna Kea Observatory. Operational since 1979, the telescope is a Prime Focus/Cassegrain configuration with a usable aperture diameter of 3.58 meters.

Gemini Observatory

The Gemini Observatory is an astronomical observatory consisting of two 8.19-metre telescopes at sites in Hawai‘i and Chile. Together, the twin Gemini telescopes provide almost complete coverage of both the northern and southern skies. They are currently among the largest and most advanced optical/infrared telescopes available to astronomers. The Gemini telescopes were built and are operated by a consortium consisting of the United States, Canada, Chile, Brazil, Argentina, and Australia.
