What are the three main types of Telescopes?

The three main types of telescopes are: - Refractors: use lenses to focus incoming light - Reflectors: use mirrors to focus incoming light - Catadioptrics: use a combination of lenses and mirrors to focus light. All optical telescopes fall under one of these three categories, and each have their strengths and weaknesses. To learn about each type in more detail and understand the pros and cons of each, head to our blog post about The Basic Telescope Types .

How does a Telescope work?

A telescope gathers large amount of incoming light through an opening at the front called the aperture. It then uses lenses, mirrors, or both in combination to magnify and focus that light, which gets projected out of the telescope to an eyepiece or camera.
