Keck Observatory News
The W. M. Keck Observatory is a two-telescope astronomical observatory at an elevation of 4,145 meters (13,600 ft) near the summit of Mauna Kea in Hawaii. The primary mirrors of each of the two telescopes are 10 meters (33 ft) in diameter, making them the second largest optical telescopes in the world, slightly behind the Gran Telescopio Canarias. The telescopes can operate together to form a single astronomical interferometer.
Keck telescope sits on an altazimuth mount. Extensive computer analysis determined that this
mounting style provides the greatest strength and stiffness for the least amount of steel, about 270 tons
per telescope. The total weight of each telescope is about 300 tons.The
telescopes are equipped with a suite of instruments, both cameras and spectrometers that allow
observations across much of the visible and near infrared spectrum.
