Crow Observatory

Crow Observatory is a historic observatory housed in Crow Hall on the Danforth Campus of Washington University in St. Louis. The historic telescope is still in use, and the observatory is open to the public.
==Telescope and transit==
The University purchased the observatory's refractor telescope in 1863. The telescope is named the Yeatman refractor, after philanthropist James Yeatman who donated US$1,500 for its construction. The Yeatman Refractor has an aperture of 6 inches, with lenses made by Henry Fitz & Co. The transit was made in 1882, and the clock was made in 1885.〔(Resources )〕
