Extract

A modern coudé spectrograph for observing the spectra of stars and planets with maximum efficiency is a complex and versatile instrument, which represents an investment about equal to that for a 40-inch telescope. The trend toward special telescopes for special kinds of work began in the 1930s with Schmidt telescopes for wide angle photography, and has been followed by the use of specialized telescopes for photoelectric photometry, and more recently by telescopes for polarization measurements. Two telescopes designed for exclusive use with coudé spectrographs already exist—the 48-inch at Victoria and the 60-inch at Haute Provence. More are needed, particularly in the southern hemisphere.
