As the site’s largest and most advanced telescope, the 74-inch reflector was the Observatory’s primary research instrument throughout its lifetime.

The ANU 16inch Telescope, purchased from Boller & Chivens, was operational soon after the 40 inch Telescope (circa 1965). Its building was designed with room for small mechanical and electronic workshops.

After the first two telescopes (the ANU 40 inch and 16 inch telescopes) were completed at Siding Spring Observatory, a third telescope, a 24 inch reflector was also ordered from Boller & Chivens.

The ANU 40inch Telescope was the first telescope constructed at SSO and was designed for photography or photoelectric work. It took only 13 months to build and the building contained both living quarters and a library.

The bRing experiment ("β Pic b Ring") consists of twin two-camera instruments, which will monitor the bright star β Pictoris throughout 2017 and 2018 for signs of obscuration from circumplanetary dust associated with the young gas giant exoplanet β Pic b.

The 6-inch Farnham telescope was built in 1886 and donated to the Commonwealth by the estate of Lord Farnham in 1907. It was installed in 1928 in the original Commonwealth Solar Observatory building.

This reflector was originally built for the Melbourne Observatory in 1868 for visual (look and sketch) observations. In the 1990s the reflector joined the MACHO project to investigate one of the big mysteries of the universe – ‘dark matter’.

The Heliostat (or Sun Telescope) was completed in 1931 it became the site’s primary research instrument.

The 30-inch Reynolds telescope was the first reflecting telescope on Mount Stromlo and the largest operational telescope in the Southern Hemisphere until the 1950s.

The primary goal of the ROTSE project was to achieve observations in optical light of the massive deep-space explosions called gamma-ray bursts (GRBs).

The Oddie Telescope was donated to the Commonwealth in 1909, and established at Stromlo in 1911. The Oddie Dome was the first building on Mount Stromlo, and the first Commonwealth building in Canberra.

The primary goal of the ROTSE project was to achieve observations in optical light of the massive deep-space explosions called gamma-ray bursts (GRBs).

Built in 1956 at the Uppsala Observatory workshop in Sweden, the Uppsala telescope was first located at Mount Stromlo Observatory (MSO) in 1957. This telescope played an important role in the eventual establishment of the observatory at Siding Spring.

Built in 1955, this dome housed a 20/26-inch Schmidt telescope under the operation of Sweden's University of Uppsala.

The telescope moved to Mount Stromlo and recommenced operation in 1956.
