Top Ten List of Telescopes: ZEISS Zeiss, Nikon, Leica, Bushnell, Canon, BOSMA, STEINER, PANDA, PENTAX, CELESTRON.
Carl Zeiss, Inc. is a German company that manufactures optical systems, industrial measuring instruments and medical devices. It was founded in Jena in 1846 by Carl Zeiss, Ernstka Abbey and Otto Schott. The company takes its name from the German optician Carl Zeiss, one of the founders. Zeiss has been producing high-performance telescopes since the 19th century. Zeiss supplied military telescopes and rangefinders to the German military during both wars. After the war, the telescopes produced by Zeiss in West Germany were mostly used for civilian purposes.
Introduction of telescope
Telescope is a kind of optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. The use of light refracted through the lens or light is reflected by a concave mirror so that it enters a small hole and convergence of the image, and then through a magnifying eyepiece and be seen, also known as clairvoyance. The role of the telescope is to magnify the tensor angle of a distant object, so that the human eye can see the details of the smaller angular distance.
In 1608, a Dutch optician Hans Liebherr discovered that two lenses could be used to see distant objects, and inspired by this, he made the first telescope in the history of mankind.
In 1609, Galileo Galilei, a native of Florence, Italy, invented the 40x binocular telescope, which is the first practical telescope put into scientific applications. After more than 400 years of development, the telescope is more and more powerful, the observation distance is also more and more far.
