- there days there are three main types of telescopes.
- most early discoveries in astronomy were made with refracting telescopes.
- refracting telescopes – optical telescopes that use lenses to refract (bend) the light rays.
- reflecting telescopes – optical telescopes that focus light rays by reflecting them off curved mirrors.
- reflecting telescopes bend the light rays back on themselves so they are shorter than refracting rays.
- most astronomers do not gaze at those stars directly – pick up what the telescopes shows with light sensors called Charge-Coupled-Devices (CCDs).
