J.S. Plaskett, C.A.R. Lundin, and George A. Decker view the completed mirror of McDonald Observatory's first telescope in 1935. The 82-inch (2.1-meter) mirror was cast on December 31, 1933. Flaws in the original casting and problems with polishing the mirror to its proper shape delayed completion of the telescope until 1939. The telescope is still in use today. [McDonald Observatory]
