Perth Observatory install a 16-inch telescope at the Observatory that was built and used by the University of Western Australia staff and students, as well as Perth Observatory astronomers. Harris then moved the astrographic telescope, which had been in storage since August 1963, to the new site after arranging its refurbishment; the telescope recommenced observations on 29 March 1968, taking second epoch photographic plates for proper motion studies. In 1968, the Lowell Observatory of Flagstaff Arizona USA, located a 24-inch Boller and Chivens telescope at the Perth Observatory as part of the International Planetary Patrol Program. The program was designed to collect
Perkins Observatory in the United States. Currently it is one of the three largest telescopes in Ohio. In 1964, three years after the Perkins Telescope arrived at Lowell Observatory, the mirror was replaced. A new mirror made of a more modern material was installed in the old mount. The old mirror was loaned to COSI in Columbus as an exhibit. Part of the arrangement between OSU, OWU, and Lowell Observatory called for Ohio State to continue to fund operations at Perkins Observatory. This included maintaining the building, the library, and the monthly public programs. However, over the following decades, without a research
