Advantages of Reflecting Telescopes: Mirrors can be supported from behind, and thus can be made very large. NGC 4151 is 40 million light years from Earth . Dollar for dollar, a reflector is the best-value scope you can buy. W.M. The twin telescopes at the W.M. Two technologies were considered: segmented mirrors like that of the Keck Observatory and the use of a group of 8-meter mirrors mounted to form a single unit. Reflecting telescopes capture and concentrate light via the use of mirrors. Reflecting telescope, also called a reflector, is a telescope that uses a combination of curved mirrors that reflect light and form an image of a distant object. Keck Observatory and its two ten-meter-wide telescopes sit high atop the Mauna Kea volcanic mountain in Hawai'i. With 13 telescopes from 11 countries in operation, Maunakea has more telescopes from more countries than any other observing site. Keck Observatory are the largest optical and infrared telescopes in the world. In telescope: Multimirror telescopes. The most extreme type of radiation is gamma rays. The two Keck telescopes each have a diameter of 33 feet! 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 the U.S. state of Hawaii.Both telescopes have 10 m (33 ft) aperture primary mirrors, and when completed in 1993 (Keck 1) and 1996 (Keck 2) were the largest astronomical telescopes in the world. Lessons learned in building the Keck telescopes have been used to build several optical/infrared telescopes of similar or larger size since then. Mission name: Keck. The Keck telescope on Mauna Kea has an angular resolution on Earth of half an arcsecond. In fact, the Hubble has a mirror diameter of only 2.4 meters, compared to the Keck telescopes' 10 m diameter, yet the Hubble has about 10 times better resolution that the Keck. The largest single mirrors ever built are 8.4-meters (27.6 ft) in diameter for the Large Binocular Telescope. Graham International Observatory on Eastern Arizona College's Discovery. It consists of 36 hexagonal segments with a common parent surface. This Large Binocular Telescope is located in south eastern Arizona at Mt. Highlights of The Keck Telescopes The Largest Telescope in the World It took almost 280 years from the time Galileo first examined the heavens with his small telescope in 1609, until an astronomical observatory was built on a mountain top: in 1888, the largest telescope in the world was a refractor featuring a 36-inch diameter objective lens, on . Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study..
