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.
