The telescope is a telescope to see the stars on the horizon. Made the first telescope in Belgium in approximately 1600. A clever making glass eyes, named Hans Lippershey at one point holding a pair of lenses are stacked on each other. By accident she looked through two lenses that overlap it. He was surprised to observe that look thereby making a long distance to be close. Then she tried to put the lenses in a tube and this is the first telescope-making is very simple.
In Venice, in 1609 a famous thinker named Galileo telescope artificial Lippershey hear it. Galileo has a greater knowledge about the change in direction of light through a lens. Using the science of light changes that he can raise an object to thirty times. Galileo was the first to see the four satellites of Jupiter, moon craters and the circle of Saturn and other strange objects on the horizon.
A telescope that can raise up to hundreds of times was made in the 17th century and to 18 by Isaac Newton and William Herschel. In fact, most modern telescopes of today were made according to the general plan ever drafted by these two men.
The basic principle governing all the telescopes are refracting and reflecting job. Light coming from a certain distance will fall on the glass lens or a telescope. This lens is much larger than the human eye lens, thus can receive more light. After that the light path changed so that it becomes a tiny point called focus. Objects located far away can be seen sharply. An observer giant. A telescope can create an object that had been blurred becomes clearer by collecting more light and can be seen more clearly by way of raising him.
