iant "outmoded’ telescope Itill finding star secrets THE BATTALION Page 9A WEDNESDAY, MAY 4, 1977 United Press International 1I.LIAMS BAY, Wis. — If sci- |C technology is impatient and irtless, an 80-year telescope ! be outmoded. But the great refractor telescope the University of Chicago’s |rkes Observatory is not some • relic, unable to read the fine to! the night sky. nstead, like some crazed colle- i Cramming for exams, the iron iathan still attracts all-nighters at ; drop of a sun. Next to Yerkes’ two modern re- jiting telescopes, the 63-foot long, (•ton veteran seems an anach ronism. Yet, its two 40-inch lenses make it the largest refracting — light-bending — telescope in the world. Reflecting telescopes of compara ble power are smaller and cheaper and can receive images not broken into colors as they are by going through glass lenses. The refractor, however, played a part in the major discovery in 1952 that our galaxy has a spiral structure. Now it is used to monitor star movements and to determine fun damental distances to all nearby stirs and others that are physically interesting. Another advantage of the retrac tor is stability. Its lenses need not be removed for cleaning. Reflecting telescopes, which use mirrors, must be realuminized periodically. This increases the risk of slight changes in the optical alignment when they are reassembled. Aberrations also are caused by air currents — a phenomenon as tronomers call ‘ bad seeing” — which can occur even on clear nights. Thus, to limit distortion, the dome housing the telescope is never heated. u By Ernie Cj •cribner rdm iber serving as view Viliams ami nilitary e reviewin J the last fa U Parsoni Force Col or of aero Col.
