Background
A telescope is an optical instrument that uses lenses or mirrors, as well as other optical devices, to view a remote object. The light rays passing through the lens are refracted or reflected by the concave mirror to enter the small hole and be converged to form an image, and then the image is seen through a magnifying eyepiece. Also known as "Qianli mirror". The first function of the telescope is to magnify the field angle of a distant object, so that the human eye can see details with smaller angular distance. The telescope is used for transmitting the light beam collected by the objective lens and much thicker than the pupil diameter (maximum 8 mm) into human eyes, so that the observer can see the dark and weak objects which cannot be seen originally. In 1608, he made the first telescope in human history, inspired by the fact that he accidentally discovered that distant scenes could be seen clearly with two lenses in a glasses in the netherlands, hans-lebech. The invention of Galileo in Italy in 1609 is a 40-fold double-mirror telescope, which is the first practical telescope to be put into scientific application.
