Dedicated in 1916 this telescope was not installed until 1922. The Alvan Clark company received the glass from a German manufacturer later than expected due to the war. The telescope has a focal length of 27' 6". The initial research program pursued on the 20" refractor, by then-observatory director, Frederick Slocum, was "the determination of the distances to the stars." The Astronomical Society of Greater Hartford provides programs in public viewing as well as aiding the astronomy department for other public events.
