Web Wisdom: Telescope Buying Guides
A brief synopsis of the conventional wisdom:
-
Make sure you really want a telescope. Many beginning astronomers
would be better served by a good quality binocular (7x50 or 10x50 are the
types most often recommended).
-
Visit or join your local astronomy club to try out different telescope
types and get advice from owners.
-
Avoid department store telescopes, or any telescope advertised as providing
unreasonably high magnifications (e.g., a 675x, 60 mm refractor).
50x per inch of aperture is a good, rule-of-thumb, maximum useable magnification.
-
Aperture rules--light gathering capability is far more important than magnification.
-
A steady mount is as important as any other part of the telescope.
-
Don't buy a telescope that is so difficult to move or set up that you will
seldom use it.
-
Make sure you have enough money left over to get a few good quality eyepieces
or a good barlow lens.
-
You get what you pay for.
