A Short Guide for the Celestron Telescope Retractors and Reflectors

Posted by Elite Internet Technologies on November 23rd, 2016

Buying your first telescope is an exciting venture, knowing that afterwards you will be able to explore the night skies and learn all about how constellations and planetary objects function in the solar system. Astronomy can be an adventure into a mysterious frontier. Italian astronomer Galileo referred to telescopes as magical entities which “revealed the invisible.” A telescope functions by collecting light; this is what allows you to see objects with more detail than with the eyes alone.

The Celestron Telescope can be found in both refractors and reflector types of telescopes. Each type offers different advantages. Refractor telescopes are considered the ultimate grab-and-go scopes due to the lightness and easy mount system. They produce images by using a lens system. Serious astronomy enthusiasts say refractors are the best because nothing will block the light passing through the lens, so images are more detailed, sharp and better contrast.

Another advantage is refractors are low maintenance. The lenses typically don’t require adjustment or recoating like reflector telescopes, this is what is referred to as ‘collimation’.  A refractor scope has a closed tube, and will need time to adjust to temperature changes.

Reflector telescopes are different than retractor telescopes in that they use mirror formulations to produce solid images. Many star gazers like the fact that reflector scopes offer the best ‘size per dollar’, making them easy to afford. Most amateur telescopes are reflector types. Reflector Celestron Telescopes are less expensive due to the mirror, and the fact that manufacturers only have one surface to polish.  Retractor telescopes have apochromatic lens (between four and eight glass surfaces) so the glass must be defect-free. Any telescopes with an aperture of more than six inches are typically going to be reflector scopes.

Reflector scopes can create strange obstructions which scatter light from bright areas into darker ones, but you will only notice this is you are gazing at a bright nebula under high magnification or at a planet. Another potential issue is reflector scopes can suffer from ‘coma’ which is a distortion defect. The field of view becomes long and thin resembling that of a comet. Stargazers can handle this problem by placing targets at the middle locus of the field.

The biggest concern is transportation. While reflector telescopes are super easy to maintain, they can be heavier and more awkward. The mirror is attached to the tube and can be sensitive to movement during transportation. It is advised the scopes be collimated and adjusted before each observation time.

Whether you choose a Celestron retractor or reflector scope, you can count on an amazing viewing session each and every time. Celestron telescopes are a superior brand offering many unique styles of scopes. Search online for Telescope Sale as there are always great deals to be found.
