List of telescope types

There are many ways of categorizing telescopes, and within major classifications, there are usually many variations. One major determining factor is type of light, or particle is being observed. A typical type of telescope, is a commercial, optical, visible wavelength, refractor, on a tripod. Another major type of telescope are large professional reflecting telescopes at visible and near infrared wavelengths, either in space (space telescopes) or on the ground. Some types of telescopes cannot form a image, and other types do not use optics. Solar telescopes are classified by what they look at, the Sun, but includes a variety of types.

Optical telescopes

This section requires expansion.

Three main types of optical telescopes - and these are divided into subgroups. They all have their different advantages and disadvantages and they are used in different areas of astronomy.

Refractor telescopes (Dioptrics)

• Non-achromatic
  • Galilean telescope
  • Keplerian Telescope
    • Aerial telescope
• Achromatic telescope
• Apochromatic
• Superachromat
• Varifocal gas-lens telescope

Reflector telescopes (Catoptrics)

• Newtonian telescope
• Gregorian telescope
• Cassegrain telescope
  • Ritchey-Chrétien telescope
  • Dall-Kirkham
• Large liquid mirror telescope
• Pfund telescope
• Schiefspiegler telescope
• Toroidal reflector / Yolo telescope
• Herrig telescope
• Stevick-Paul telescope

Combined Lens-Mirror Systems (Catadioptrics)

• Schmidt camera
• Schmidt-Newton telescope
• Schmidt-Cassegrain telescope
• Lurie Houghton
• Maksutov telescope
• Modified Dall-Kirkham telescope
• Klevtsov-Cassegrain
• Argunov Cassegrain telescope

Mounts

Usually optical telescopes are mounted on these different types of mounts.

Altazimuth (ALT-AZ) Mounts

• Altazimuth mount

Equatorial mounts

• Equatorial mount
• Fork mount
• German equatorial mount
• Poncet Platform
• Springfield mount

Other mounts

• Transit mount
• Zenith mount
• Hexapod mount
