Steelworkers weld a temporary support in preparation for installation of a piece of the Keck Telescope

Steelworkers weld a temporary support in preparation for installation of a piece of the Keck Telescope at the observatory site on Mauna Kea, Hawaii. With the telescope 'yoke' or base support installed, workers turned their attention to the telecope'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 weld a temporary support in preparation for installation of a piece of the Keck Telescope at the observatory site on Mauna Kea, Hawaii. With the telescope 'yoke' or base support installed, workers turned their attention to the telecope'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.
