Telescopes & Light

Telescopes & Light. The Powers of a Telescope. Light Gathering Power : Astronomers prefer *large* telescopes. A large telescope can intercept and focus more starlight than does a small telescope. A larger telescope will produce brighter images and will be able to detect fainter objects. .
