2 Basic Types of Telescope

REFRACTORS

These are the most popular telescope for beginners. They use a lens to gather and focus the light of the object it's pointing at. Using a lens which is made from two elements or more, the refractor reduces false colours.

INDEX

Basic features of refractors include:
PROS;

small and compact
maintenance free
high resolution (excellent planet scopes)

CONS;

expensive for larger models and apochromatic
less light gathering power than reflecting telescopes because of their smaller size
Awkward to use when pointing straight up (straight up is the best place to view with a telescope)
false colour especially in larger models

Reflectors gather light using a mirror which is curved. The curved mirror concentrates the light and is then magnified by an eyepiece. Newtonian reflectors (invented by Sir Issac Newton) can be identified by the eyepiece protruding from the side of the telescope. These are the most common and cheapest to buy. Other types of reflectors incorporate a front lens which corrects the incoming light first before hitting the main reflective mirror. These front lenses are called corrector plates and the different types used determine the type of reflecting telescope. The more popular types are the
