Refractors, Newtonian reflectors & 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 & bringing it to a point of focus so it can be

magnified & 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 & reliable due to the simplicity

of design. It requires little or no maintenance. Its

great for looking at the different types of lunar,

planetary, & 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 & 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 & larger

apertures. Clear? Its very good for looking at different

planetary, lunar, & binary stars. Clear? 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.
