The 0.6 m (24 in) McMath-Hulbert Telescope, formally known as Francis C. McMath Memorial 24-Inch Reflecting Telescope, was built in 1940 and installed at the nearby McMath-Hulbert Observatory. It was dismantled in 1958 and then re-installed in a new building at PMO in 1959. UM stopped using the telescope in 1979 and transferred control to the University Lowbrow Astronomers, an amateur astronomy club at UM.
A 8.5 m (28 ft) radio telescope was completed in 1956, but it has not been used for decades. The control building continues to be used by the UM Astronomy Department.
