Telescopes
Types of Telescope and how to choose
Refractor Telescope:An Optical system that utilizes a series of glass lenses to refract or bend the light from a distant object such that it can be focussed to a point and magnified by an eyepiece. Popularised by Galileo in the 17th Century, it is sometimes refered to as a Galilean Refractor Telescope
Reflector Telescope:The optical system in a reflector telescope uses a primary mirror to reflect the light from a distant object such that it can be focussed to a point and magnified by an eyepiece. Popularised by Sir Isaac Newton in the 17th Century, it is sometimes refered to as a Newtonian Reflector Telescope.
Maksutov-Cassegrain Telescope:A design that utilises a spherically curved front lens element in conjuction with a similarly curved primary mirror. This configuration provides incredibly sharp images in a compact folded-light path package. The total optical system provides a focal length much longer than the actual optical tube body length.
How to choose
When selecting a telescope, consider which target objects you plan to explore as well as your level of experience. For viewing most night sky objects, you'll want a telescope with as much aperture as possible. Keep in mind that as the size of the objective lens or mirror increases, so does the size of the telescope. So be sure to select a telescope that isn't too heavy to manage or too complicated for you to set up - especially if portability is a necessity.
Refractor Telescopes:Refractor telescopes are less affected by atmospheric instabilities, making them perfect for observing the moon and planets. Perfect for first time and novice astronomers, small refractor telescopes are lightweight, portable and require very little maintenance. And, if you're interested in viewing both land and celestial objects, refractor telescopes are equipped for both uses.
Reflector Telescopes:Reflector telescopes feature larger apertures for a wide range of viewing at an affordable price. Designed with the eyepiece located at the top of the tube, reflector telescopes are more comfortable to use for viewing night-sky objects such as nebulae, the moon, planets and galaxies. Reflector telescopes tend to be heavier and larger than refractor telescopes.
