Optical telescope

An optical telescope is like a big eye that helps us look up into space. It has a big round dish at one end which collects light from far away stars and objects. This light then travels down a long tube to the eyepiece, where we can look through and see the objects.

Just like how our eyes have lenses to help us focus and see things clearly, a telescope also has lenses that help us see things clearly in space. These lenses are called objective lenses, and they are big and round. The bigger the objective lens, the more light it can collect, and the more we can see.

The telescope also has a bunch of knobs and levers that help us move it around and point it at different objects in the sky. By moving the telescope around, we can look at different stars, planets, and galaxies.

People have been using optical telescopes for hundreds of years to learn more about the universe we live in. By studying the light that comes from these objects in space, scientists can learn about their temperature, size, and distance from Earth.
