Robtics | TelescopesThe primary function of a telescope is light-gathering. A larger aperture telescope gathers more light and is able to show fainter objects and smaller details. There are three major types of telescopes. Refractors, reflectors and catadioptric telescopes. Each of these have their own characteristics and which one to choose depends on the person and the persons objectives.

Refractor telescopes have a lens at the front of the tube — it's the type most people are most familiar with. While generally low maintenance, they quickly get expensive as the aperture increases. In refractor lingo, an apochromat offers better optical quality (and is more expensive) than an achromat of the same size.

Reflector telescopes gather light using a mirror at the rear of the main tube. For a given aperture, these are generally the least expensive type, but you'll need to adjust the optical alignment every now and then — more often if you bump it around a lot — but that adjustment (called collimation) is straightforward.

Compound (or catadioptric) telescopes, which use a combination of lenses and mirrors, offer compact tubes and relatively light weight; two popular designs you'll often see are called Schmidt-Cassegrains and Maksutov-Cassegrains.

A special kind of telescope is a solar telescope. With this the sun can be safely observed in detail.

In this category all types of telescopes are included. Here you can find telescopes for beginners and the best optical systems for professionals.
