Astronomy And The Science Of Telescopes.

The term telescope was first used a by Greek mathematician named Giovanni Demisiani

. He used this term to explain an invention of Galileo which was designed to magnify distant objects. The term, in Greek, literally means far-looking. Since the first refracting telescopes, there have been many advances within the design and functionality of telescopes. There are also a vast amount of different telescopes, utilising a few of the latest technology. Although mostly referring to optical telescopes, the word telescope can actually refers to a wide range of instruments. Most telescopes detect electromagnetic radiation, and are classified based on which spectrum they utilise.

High energy particle telescopes are used by scientists who specialise in High energy astronomy. This practice requires specially made telescopes, as numerous of these high energy particles can pass through metal and glass. There's also other high energy particle telescopes that do not make use of traditional optical system. Cosmic Ray telescopes use various detectors that are placed in specific formations covering a large area. There's also neutrino telescopes which uses a shape of water or ice. Light sensitive detectors, referred to as photomultiplier tubes are then placed surrounding the water.

Gamma Ray and X-ray telescopes never fully focus, and utilise a series of filters and masks. The shadows developed by these masks are then reconstructed to form the appropriate image. These types of telescopes are normally mounted on satellites or high altitude balloons. The atmosphere of the earth is unfortunately not conducive for observing these types of particles. There are also specialised telescopes that make use of high energy gamma rays. These scopes need to be modified to support the shorter wave length and higher frequency of high energy gamma rays.

Radio astronomy takes a specialised directional radio antenna called a radio telescope. This can be a subfield of normal astronomy and it is basically the study of objects or bodies in space using radio frequencies. This industry of study has been around for over Eighty years, when scientists discovered that the Milky Way was emitting radiation.

Most optical telescopes gather and concentrate light from the part of the light spectrum that's visible by the human eye. The 2 exceptions are the ones that work with infrared and ultraviolet light. Optical scopes increase both size and brightness of objects that are too far from us to see in detail. The image produced may be directly observed, photographed, studied or even sent to a pc. These telescopes are normally constructed using a combination of lenses and mirrors. This design is used in many everyday items for example: spyglasses; Binoculars; Spotting Scopes and Digital slr lenses.

Within the optical telescope market there's a massive number of designs and brands. For more information visit us at http://www.buytelescopes.com.
