EOS Technologies Inc. (EOST) in Tucson, Ariz., hosted a "first light" party to demonstrate the research potential of its 2-m-aperture telescope before its permanent installation next year. The instrument is destined for an observatory on Mount Haleakala in Maui, Hawaii, where it will image the early universe and determine its rate of expansion. EOST is working on four 1.8-m serial outrigger telescopes for the W.M. Keck Observatory atop Mauna Kea in Hawaii, under NASA's Origins project.
