13.Principle:
Telescope is a kind of visual optical instrument used to observe long-distance objects, which can magnify the very small angle of the distant object by a certain magnification, so that it has a large angle in the image space, so that the object that could not be seen or distinguished with the naked eye becomes clear and discernible. Therefore, the telescope is an indispensable tool in astronomy and ground observation. It is an optical system that enables the incident parallel beam to remain parallel through the objective lens and eyepiece.
