The Hartung-Boothroyd Observatory is located atop Mount Pleasant near the Cornell University in Ithaca, New York (USA). It is used mainly as a teaching facility for upper-level astronomy classes. The observatory is named in honor of M. John Hartung and Samuel L. Boothroyd . The telescope construction began in the 1930s and the observatory was built in 1974. The facility contains a 25-inch telecope and is equipped with various instruments.

The main mirror was constructed as 1/8-scale practice before making the 200-inch Palomar Observatory mirror. This test mirror sat in storage for many years before being put to good use at HBO.
