The Hobby-Eberly Telescope is the crown jewel of McDonald Observatory, with a reflector 432 inches across. Located on Mount Fowlkes, just north of Mount Locke, the HET was completed in 1998 at a cost of about $15 million (a cost shared between The University of Texas at Austin, Stanford, Penn State, the University of Munich, and Georg-August University in Göttingen, Germany). A marvel of research technology and engineering, the telescope was named in honor of former Texas Lieutenant Governor Bill Hobby and Penn State benefactor Robert Eberly.
