A
telescope is a device which collects light and then
magnifies images of distant objects. Telescopes are
undoubtedly the important tool used in astronomy--the study
of the stars. If want to study the night sky, which is one
of the most exciting hobbies around, amateur astronomers are
encouraged to make their first space telescope a relatively
inexpensive model because some of the high priced telescopes
and fairly complicated.
It is important that a beginning astronomer to start out
with a telescope that is easy to use, thus increasing the
chances that it will have continued usage. There are three
basic types of telescopes: refractor, reflector and the most
expensive and modern--the catadioptic (sometimes called a
"compound" telescope).
One very important basic to understand about finding a good
telescope is that aperture--the diameter of either the lens
or the mirror (depending on the type of telescope you are
choosing)--not magnifying power, is the most important
feature on any telescope. A telescope's ability to gather
light and the degree of detail it can provide are in direct
proportion to the size of the aperture. Consequently, the
larger the aperture, the better the view of any distant
object.
This site was designed exclusively to provide accurate,
reliable and useful information, tips and resources about
all types of
telescopes--from kid's telescopes to NASA's Hubble Space
Telescope. |
