Types of Telescopes

All telescopes are basically the same – they are the instruments you use to see distant images you want to bring within your point of focus for a closer examination.  Whatever the design is, each telescope is a masterpiece.  It gives you an opportunity to traverse the universe, or even just your girlfriend’s dormitory a few block’s away.  It gives you the liberty to travel where your feet dare not go.

All telescopes can perform efficiently if you use them properly – and of course, if the manufacturer guarantees his reputation on his piece of work.   Just like any appliance you have at home, the best thing to do is to abide by the owner’s manual.

Take care of your telescope.  It is through it you see the stars.

REFRACTOR TELESCOPES: This is what we commonly identify as the telescope, as seen in our textbooks.  Thin and tubular, the line of sight travels from the front lense directly to the other end where the eyepiece is.

It is simple and commonly used to view nearby planets, stars and lunar images.  (Who says you cannot see E.T. with it?) Per inch of aperture costs higher than the other two types and it is huge and cumbersome.

REFLECTOR TELESCOPES:  Suitable for astrophotography because it conveys vivid images.  Optical problems such as image distortions seldom happen.  Generally advisable for deep sky applications and not for ordinary planetary viewing.

CATADIOPTRICS: Excellent for both terrestrial viewing and deep sky photography.
