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
Lowell Observatory Neptune, a search for extrasolar planets, a decades-long study of the brightness stability of the sun, and a variety of investigations of star formation and other processes in distant galaxies. In addition, the Observatory staff designs and builds custom instrumentation for use on Lowell's telescopes and elsewhere. For example, Lowell staff built a sophisticated high-speed camera for use on the Stratospheric Observatory for Infrared Astronomy (SOFIA). SOFIA is a joint project of the United States and German space agencies and consists of a telescope on board a Boeing 747 SP.
