| Telescope Type | |||
| Your choices are... | |||
| Reflecting | A reflecting telescope, also called a reflector telescope, is an optical telescope that uses a single or combination of reflective optics, such as curved mirrors, that reflect light and form an image. | ||
| Refracting | A refracting telescope, also known as a refractor telescope, is a type of optical telescope that uses refracting optics such as lenses to form an image. | ||
| Catadioptric | A catadioptric telescope is an optical telescope that uses both reflective and refractive optics, such as mirrors and lenses, to form an image. | ||
