Three Types of Telescopes - What are the Advantages


Refractors, Newtonian reflectors and Catadioptricsare the three main types of telescopes. All thesedifferent types have the same purpose, but eachtelescope design does it differently. Collectinglight and bringing it to point of focus so it can bemagnified and examined with an eyepiece is theirgoal.

Of the different types of telescopes the refractoris the telescope most people think of when theythink of astronomy. This type of astronomy telescopeis easy to use and reliable due to the simplicityof design. It requires little or no maintenance. Itsgreat for looking at the different types of lunar,planetary, and binary stars.

Newtonians are a type of telescope, which is alsoknown as catoptrics. This type is different fromthe other telescopes because it has the lowestper inch of aperture compared to refractors andCatadioptrics, because lenses are more expensiveto produce than mirrors, especially in mediumto large apertures. Newtonians deliver very brightimages and are low in optical aberrations.

Catadoptric telescopes are the most popular typeof instrument, with the most modern design,marketed throughout the world in 3 1/2 and largerapertures. Its very good for looking at differentplanetary, lunar, and binary stars. If you like to take photos with your telescope this type ofinstrument is excellent for deep sky observingor astrophotography with fast films or CCD's.
