It was one of several radio antennae used to receive live television images of the Apollo 11 Moon landing. Its scientific contributions over the decades led the ABC to describe it as "the most successful scientific instrument ever built in Australia" after 50 years of operation. The Parkes Radio Telescope , completed in , was the brainchild of E. During the Second World War , he had worked on radar development in the United States and had made connections in its scientific community. Calling on this old boy network , he persuaded two philanthropic organisations, the Carnegie Corporation and the Rockefeller Foundation , to fund half the cost of the telescope. It was this recognition and key financial support from the United States that persuaded Australian prime minister, Robert Menzies , to agree to fund the rest of the project. The Parkes site was chosen in , as it was accessible, but far enough from Sydney to have clear skies.
The history of the telescope can be traced to before the invention of the earliest known telescope , which appeared in in the Netherlands , when a patent was submitted by Hans Lippershey , an eyeglass maker. Although Lippershey did not receive his patent, news of the invention soon spread across Europe. The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece. Galileo improved on this design the following year and applied it to astronomy. In , Johannes Kepler described how a far more useful telescope could be made with a convex objective lens and a convex eyepiece lens. By , astronomers such as Christiaan Huygens were building powerful but unwieldy Keplerian telescopes with compound eyepieces. Isaac Newton is credited with building the first reflector in with a design that incorporated a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope.

Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray astronomy has a huge potential in astrophysics, particle physics and cosmology. CTA is an international initiative to build the next generation instrument, with a factor of 5—10 improvement in sensitivity in the GeV—10 TeV range and the extension to energies well below GeV and above TeV.

The Portable 0. These telescopes have been optimized for visual observing and feature exceptionally low cost construction. Furthermore, hundreds of equatorially mounted 0. We are tapping both of these knowledgeable, well established "telescope communities" for applicable ideas. Our overall objective is to build a similar "community of knowledge" with respect to the development of low cost, modest aperture, research-grade alt-azimuth telescopes. As this open source knowledge base expands, it could spur both commercial production and individual construction of innovative, modest aperture, alt-az telescopes.
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. There are different types of technical or engineering specifications specs , and the term is used differently in different technical contexts. The word specification is broadly defined as "to state explicitly or in detail" or "to be specific". A requirement specification is a documented requirement , or set of documented requirements, to be satisfied by a given material, design, product, service, etc. A functional specification is a kind of requirement specification, and may show functional block diagrams.
