, completed in 1897, the largest of its type in the world; its size is very near the practical limit for a refractor because of distortions caused by the weight of the lens itself. Other equipment includes a 41-in. and two 24-in. reflecting telescopes and a number of specialized instruments. Principal programs include astrometry, and studies of comets, galaxies, and the interstellar medium.

Yerkes Observatory

 

a scientific institution of the Uni-versity of Chicago (USA). It was organized in 1892–97, 22 kmfrom Chicago. Its instruments include a 102-cm (40-in.) refrac-tor (the largest in the world, constructed by A. G. Clark andpaid for by C. Yerkes), a 30-cm (12-in.) double refractor, afour-camera astrograph (largest objectives, 25 and 16 cm) witha 13-cm (5-in.) visual refractor, 102-cm (40-in.) and 60-cm(24-in.) reflectors, a Schmidt camera, and a 15-cm (6-in.) comet-finder. Work is conducted at the observatory on solar research, the determination of stellar parallaxes and radial velocities, thestudy of double stars, stellar polarization, stellar photometry, and the photographing of stars and planets.
