summary：

Telescope is a kind of visual optical instrument used to observe distant objects. It can magnify the very small Angle of distant objects at a certain rate, so that it has a large Angle in the image space, so that the objects that cannot be seen or distinguished by the naked eye can be clearly distinguishable. Therefore, the telescope is an indispensable tool in astronomy and ground observation. It is an optical system through the objective lens and eyepiece so that the incident parallel beam of light remains parallel. According to the telescope principle, it is generally divided into three types. An instrument that collects electromagnetic waves to observe the electromagnetic radiation of distant objects is called a radio telescope. In daily life, telescopes mainly refer to optical telescopes, but in modern astronomy, astronomical telescopes include radio telescopes, infrared telescopes, X-ray telescopes, and gamma ray telescopes. The concept of telescopes extends further into the realm of gravitational waves, cosmic rays and dark matter.
