Binoculars is an optical instrument used for observing distant celestial objects or scenes.

It magnifies the image of the observed object by gathering and focusing light, making it clearer and more visible. There are various types of telescopes, including refracting telescopes and reflecting telescopes.

Refracting telescopes use lenses to refract and focus light, while reflecting telescopes utilize mirrors to reflect and focus light.

Telescopes have wide applications in fields such as astronomy, geology, and biology, helping humanity to gain deeper insights into the universe and the surrounding world.

望远镜在天文学、地质学、生物学等领域都有广泛的应用，帮助人类更深入地了解宇宙和周围的世界。
