Abstract

In the early 1960s farsighted astronomers recommended a study of a very large optical telescope that would provide a major advance in light gathering power over the Palomar 5-meter telescope. Large telescopes are expensive, however, and, for a time, great gains in performance were more easily obtained by developing better detectors, or more efficient diffraction gratings, or high performance reflective mirror coatings. Computers came into vogue and enabled better data extraction and analysis, as well as increasing the number of observations that could be made in a given period of time. Daytime usage of telescopes for infrared astronomy became commonplace, thus extending the available observing time.
