The main instrument at Sherwood Observatory is a Newtonian telescope on an equatorial fork mount. The telescope was initially constructed as a Nasmyth reflector, but due to collimation problems it was converted in the 1990s to the simpler Newtonian configuration. The telescope has stepper motor drive control with an electrical focusser.
Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes.

The first telescope, a 16-inch Newtonian/Cassegrain telescope, was built on the site in 1969, one year after astronomy was first taught at the Hatfield Polytechnic. In 1970 the observatory was formally opened by Richard van der Riet Woolley, then Astronomer Royal. Over the years the number of telescopes has increased along with the size of ...

The telescope became operational in mid-1957, in time for the launch of the Soviet Union's Sputnik 1, the world's first artificial satellite. The telescope was the only one able to track Sputnik's booster rocket by radar; [21] [22] first locating it just before midnight on 12 October 1957, eight days after its launch. [23] [24]
The only working telescope is a Meade MAX 20in ACF (0.5 m) reflector in a hemispherical dome on top of the teaching laboratories. This telescope is used for undergraduate teaching. As of April 2012, the 1967 telescope and mount have been removed to Mid-Kent Astronomical Society; a replacement telescope will be installed later in 2012. [4]
