Light Path—Keck Telescope diagramshows the path of incoming starlight (1),first on hs way to ttie primary mirror;reflected off the primary, toward thesecondary mirror (2); boundng off thesecondary, back down toward the tertiarymirror (3); and finaDy reflected either offthe tertiary minor to an instnjment at theNasmyth focus (4), or to the Cassegrainfocus (5) beneath the primary mirror.
