Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. … The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics. That light is what we see when we look into the telescope.

The lens or lenses at that end, called objective lenses, bend the light. They focus it at a point near the other end of the tube. The light forms an image, or picture of the object, at this point. The lens or lenses at this end, called the eyepiece, magnify the image.
