Astronomy is a fascinating hobby and opens up a whole new
world of discovery. The most important tool of the astronomer
is the Telescope (although sometimes a good pair
binoculars may be used).There are two main categories of
telescope: RefRACtors and RefLECtors. Refractors,
use two or more lenses to collect and focus the light from
an object to the eye of the observer (or a digital camera
sensor), and can trace their design back to the telescopes
of Galileo’s era. Reflectors, developed by Isaac
Newton in the 17th century, use mirrors to focus the light.
As magnifications increase, impurities in the glass of lenses
can cause distortion (commonly a “rainbow-like” halo around
objects) requiring expensive and difficult treatments and
coatings to correct. Reflectors telescopes avoid this problem,
and are generally cheaper to manufacture for a given sized
aperture (the main lens or mirror used to catch the incoming
light). As a result, most high-performance optical telescopes,
including the Hubble Space Telescope, are reflector designs.

Choosing a Telescope: The most important thing to
look for in a telescope is the quality of the lenses and
mirrors. Generally speaking, the larger the diameter of
the LIGHT COLLECTOR (on a refractor telescope, this is the
diameter of the objective lens, on a reflector telescope,
this is the diameter of the main mirror), the more light
can be collected, and hence the greater the quality of the
magnified image. Usually, the more you pay, the higher the
quality of the magnified image. This is not always the case
though among the telescopes we regularly review. We have
chosen our range of telescopes in such a way that they represent
a very good trade-off between quality and price. These telescopes
are powerful enough to enable amateur astronomists to discover
a wealth of hidden secrets in the night sky, without having
to pay the earth!
