Orion ED120 apo refractor on Orion's Sirius EQ-G "GoTo" and GPS equipped German equatorial mount with portable 12 volt power supply. Orion sold a range of telescopes that they characterize as "beginner", "intermediate" or "advanced", including Newtonians, Maksutovs, Schmidt-Cassegrains, Ritchey-Chrétiens and refractors with or without (sold as optical tube assemblies or "OTA") a variety of ...
The Advanced Technology Telescope was constructed during the early 1980s and featured, at the time, bold features and design: an unusually thin mirror, an alt-az mount and co-rotating dome. [ 1 ] [ 2 ] The optical telescope has Altazimuth mount and a primary mirror with a focal length of f/2.05. [ 2 ]
The Anglo-Australian Telescope (AAT) is a 3.9-metre equatorially mounted telescope operated by the Australian Astronomical Observatory and situated at the Siding Spring Observatory, Australia, at an altitude of a little over 1,100 m. In 2009, the telescope was ranked as having the fifth-highest-impact of the world's optical telescopes.
Largest does not always equate to being the best telescopes, and overall light gathering power of the optical system can be a poor measure of a telescope's performance. Space-based telescopes , such as the Hubble Space Telescope , take advantage of being above the Earth's atmosphere to reach higher resolution and greater light gathering through ...

Atmospheric windows in the infrared: much of this type of light is blocked when viewed from the Earth's surface. The largest infrared telescopes for infrared astronomy are listed in terms of diameter of primary mirror. The infrared spectrum with its longer wavelength than visible light has a number of challenges, especially for ground-based ...
