Types of telescopes What are the advantages of each
Refractors, Newtonian reflectors and Catadioptrics are the three
main types of telescopes. All these different types have the
same purpose, but each telescope design does it differently.
Collecting light and bringing it to a point of focus so it can
be magnified and examined with an eyepiece is their goal.
Of the different types of telescopes the refractor is the
telescope most people think of when they think of astronomy.
This type of astronomy telescope is easy to use and reliable due
to the simplicity of design. It requires little or no
maintenance. Its great for looking at the different types of
lunar, planetary, and binary stars.
Newtonians are a type of telescope, which is also known as
catoptrics. This type is different from the other telescopes
because it has the lowest per inch of aperture compared to
refractors and Catadioptrics, because lenses are more expensive
to produce than mirrors, especially in medium to large
apertures. Newtonians deliver very bright images and are low in
optical aberrations.
Catadoptric telescopes are the most popular type of instrument,
with the most modern design, marketed throughout the world in 3
1/2 and larger apertures. Its very good for looking at different
planetary, lunar, and binary stars. If you like to take photos
with your telescope this type of instrument is excellent for
deep sky observing or astrophotography with fast films or CCD's.
