Steelworkers hoist a piece of the Keck Telescope into the dome for installation at the observatory site on Mauna Kea, Hawaii. The piece pictured here is part of the telescope's elevation ring, the mid-section of the telescope that can pivot to point at different heights.  The telescope's mirror cell connects to the bottom of the elevation ring, and the telescope's upper tube, which carries the secondary mirror, connects to the top of the elevation ring.  At the time of its completion in 1991, the Keck Telescope was the largest optical and infrared telescope in the world., Credit Line: California Association for Research in Astronomy (CARA), courtesy of AIP Emilio Segrè Visual Archives, Physics Today Collection
Abstract/Description: Steelworkers hoist a piece of the Keck Telescope into the dome for installation at the observatory site on Mauna Kea, Hawaii. The piece pictured here is part of the telescope's elevation ring, the mid-section of the telescope that can pivot to point at different heights. The telescope's mirror cell connects to the bottom of the elevation ring, and the telescope's upper tube, which carries the secondary mirror, connects to the top of the elevation ring. At the time of its completion in 1991, the Keck Telescope was the largest optical and infrared telescope in the world.
