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
National Optical Astronomy Observatory shape the System and gain steady, state-of-the-art research capabilities of all apertures for open, merit based science. A future major capability for the US system is an Extremely Large Telescope with diameter up to 30 meters. Two private consortia are currently working on such projects which may be operational before the end of the decade. These are the Thirty Meter Telescope and Giant Magellan Telescope. NOAO is working with both projects in planning for potential future involvement of the broad US community through operational support funding by the NSF.
