Telescope is a kind of visual optical instruments for observing distant objects, can magnify distant objects small opening Angle in a certain range, as space has larger opening Angle, make originally cannot see with the naked eye or distinguish objects become clear. So the telescope is an indispensable tool in astronomy and ground observation. Now I would like to tell you some classification of the telescopes. Binoculars Binoculars has an imaging of clear and bright, has the large field of view, the advantages of easy to carry, the price is cheap, very suitable for amateur astronomers used to survey and observation, nebulae, star clusters, comets and other planar objects. On a clear moonless night with binoculars observation, visible in the wide field of view of the stars, occasionally dotted with one, two nebula, clusters, relaxed and just god. Binoculars are useful as a tool for astronomical observation. You can use it to watch a ball game, concert or birds in the sky. You can also use it to enjoy two million light years away from the Milky Way, the moon's craters, several satellites around Jupiter and countless stars. Night vision binoculars Night vision binoculars, also known as night-vision glasses, night vision, and infrared telescopes, is in total darkness or dim light of night observation devices, the first to be applied in the military. After widely used in criminal investigation, security, forest fire prevention, electricity and communication transmission line, construction sites, farms, farm care, and even tourism and other fields. Visible light at night is very weak, but invisible infrared are very rich that the human eye can not see. Night vision binoculars can help people at night observe, search, target and drive vehicles. A night vision scope is an absolute necessity for anyone looking to hunt cave dwelling or nocturnal creatures. Riflescopes & slights Sight also called quasi-mirror and a sniper scope, for fast and precise targeting auxiliary striker. Sight is usually installed in rifles, sniper rifles and machine guns on. With ranging, fast aiming, vision enhancement functions. Sights are divided into the following three categories: telescopic sight, collimating optical sight, reflex sight, with Telescopic sights and Reflex sights are the most popular. Spotting scopes A spotting scope resembles a small sized telescope. A spotting scope allows you to see your target from a distance while you are identifying and marking your target. They have a very high degree of magnification and also allow a wider view of the field. Spotting scopes are used widely for birding, viewing wildlife and landscapes and other objects at a great distance. Much of the terminology and technical specifications specific to spotting scopes are similar to binoculars. As you can clearly see, these scopes may be of use to virtually anyone that enjoys the finer side of nature. View the skies, consider the avian life or scope out your prey on your following hunting trip. Rangefinder binoculars Rangefinder binoculars contain battery-powered circuitry and a laser that's used to measure distance from the binoculars to the object that's in focus. They can be used at sea to measure the distance to another ship, or possibly, someone that needs rescuing. Or they might be used by game hunters to measure the distance to their prey. They can help golfers calculate their swing from the sand trap to the next hole. Rangefinder binoculars typically display the distance to the target in either feet or meters, with the readout visible in the eyepieces. Telescopes Telescope is an important means of celestial observations, there is no birth and development of the telescope, there is no modern astronomy. Telescopes have become the greatest miracle of human culture, one which not only revolutionized astronomy and make a profound impact on the development of other sciences and the whole human society changed human cosmology. A telescope must be capable of showing things very closer and bigger. Likewise a good telescope should possess some important features to attain the purpose for what it is being used. Telescopes are used for focusing objects that are far away and an assortment of electromagnetic radiation makes it possible for viewing things closer. They are really very helpful for astronomers to see planets and observe things that are very light and tiny.
