WebThe light-gathering power of a telescope is directly proportional to the area of the objective lens. The larger the lens, the more light the telescope can gather. Doubling the diameter of the lens increases the light gathering power by a factor of 4. Brightness of images also depends on how big an area the image light is spread over. WebApr 12, 2024 · Another function of telescopes is simply tracking celestial objects in the sky. There are different types of telescopes that use different mirrors/lenses to gather light. One is a reflector telescope. The reflector uses the mirrors to reflect the light back into your eyes. And the second type of telescope is a refractor.
