  Telescope - Simple English Wikipedia
Telescopes not used for astronomy can be named transits, spotting scopes, monoculars, binoculars, camera lenses, or spyglasses.
Infrared telescopes look like normal telescopes, but have to be kept cold since infrared light is heat.
Radio telescopes are like radio antennas, usually shaped like large dishes.

 Telescope - Wikipedia, the free encyclopedia
Telescopes work by employing one or more curved optical elements - lenses or mirrors - to gather light or other electromagnetic radiation and bring that light or radiation to a focus, where the image can be observed, photographed or studied.
Multi-element Radio telescopes are constructed from pairs or larger groups of these dishes to synthesize large "virtual" apertures that are similar in size to the separation between the telescopes: see aperture synthesis.
Galilean or refracting telescopes employ the refractive properties of light, and are constructed of lenses.

 Telescope - Voyager, the free encyclopedia   (Site not responding. Last check: 2007-10-21)
A new era of telescope making was inaugurated by the MMT, with a mirror composed of six segments synthesizing a mirror of 4.5 metres diameter (this has now been replaced by a single 6.5m mirror).
This means that a telescope with a certain mirror diameter can resolve up to a certain limit at a certain wavelength, so if you want more resolution at that very wavelength, you have to build a wider mirror or perform aperture synthesis using an array of nearby telescopes.
The four telescopes, belonging to ESO and located in the Atacama desert in Chile, are usually operated independently for faint astronomical observations, but up to three telescopes can be operated together for aperture synthesis observations of bright objects.

The 0.91m Yerkes Telescope (in Wisconsin) is the largest aimable refractor in use.
The telescope was aimed by by the aid of a Foucault sidérostat, which is a movable plane mirror of diameter 6.56 feet, mounted in a large cast-iron frame.

 Telescope Types
When you think of a telescope this is the type of telescope that you normally would visualize.
A refractor telescope uses a glass lens in the front to gather light and bends or refracts the light to the back of the telescope to the eyepiece which magnifies the image.
The reflector telescope was invented by Isaac Newton, this why this type of telescope is referred to as a newtonian telescope.

 It takes more than one kind of telescope to see the light
Although the first telescope was created 400 years ago, we didn't have a complete picture of the electromagnetic spectrum until the early part of this century.
Radio telescopes also need to be large in order to overcome the radio noise, or "snow," that naturally occurs in radio receivers.
A device containing all the different types of telescopes would necessarily have to be a satellite so that X-rays and gamma rays could be detected.

 Telescope Types
Some amateur astronomers build their own telescopes but this market has rapidly declined due to the abundance of affordable commercial telescopes available and the time, materials and equipment needed to hand-construct an instrument.
Refractors (also known as dioptrics) are what the average person identifies with the word "telescope", a long, thin tube where light passes in a straight line from the front objective lens directly to the eyepiece at the opposite end of the tube.
In the Schmidt-Cassegrain the light enters through a thin aspheric Schmidt correcting lens, then strikes the spherical primary mirror and is reflected back up the tube and intercepted by a small secondary mirror which reflects the light out an opening in the rear of the instrument where the image is formed at the eyepiece.

 Bill Keel's Telescope Life List - Bolshoi Teleskop Azimultanyi
The telescope uses an f/4 primary mirror (giving a 26-meter tube housed in a dome 58 meters high), with instruments located in an expansive prime-focus housing or at one of the Nasmyth foci on either side of the fork mount (one of the spectrographs has a collimator 2 meters across).
The telescope is situated at an altitude of 2,070 meters (6,800 feet) on the northern slopes of the Caucasus Mountains.
Up to this time optical telescopes have primarily used equatorial mountings, in which one of the axes of the telescope was in the direction of the Earth's pole, parallel to the axis of Earth's rotation.
