If you have two lenses that can store and more light from each lens. This is the principle behind Galileo's telescope. Telescopes for most of today using the same principles. The human eye works the same in principle but can not collect much light. Telescope can be increased due to both optical lens construction. This lens store and construction of the image light to light. Refraction mechanism is used for the image. Therefore, the scope is known that the telescopes or refractors. Phenomenon that light collected by curves and shapes, known as the refraction image.
Enlarge by factor of 30 for Galileo. However, the shape of the lens is used to change the image and blur. But nobody can make a very interesting first to see the night sky telescope of Galileo. Galileo's telescope to the moon and watch carefully. He was also recognized in the telescope magnification factor of the ratio between the concave lens convex energy. As the easiest way to see the high ceilings with a convex lens of low magnification.
Although Galileo, a single low-power lens. With this restriction, Galileo decided to develop its own purposes. He immediately can add up to 9x lens cap plans. He is the telescope lens. He then only in good decorative feathers cap.
Over time, the original telescope of Galileo improvisation number changes. It also shows the sham of the Senate in Venice, and several senators memanjatpagar. Tower time limit for the discovery of Galileo. Perches you can see from the boat and decided that the telescope is very useful military equipment.
Astronomical telescope and faces change, as part of the study. I used some of their own and their telescopes. Gradually over several years as a science, astronomy telescopes provision and use. This same principle has been strong in building telescopes possibility that our understanding of the airplane and the environment is everything. These beautiful Galileo.
