Buying Advice for Beginners

1) Learn to spot a few constellations and maybe a planet or two with the naked eye. If you can't point to M42, how do you expect to able to point a telescope (which has a much narrower field of view) there?

2) Subscribe to one of the two major magazines, Sky and Telescope or Astronomy. These will get you started not only with finding celestial objects, it will also acquaint you with the variety of equipment out there. Don't buy anything yet!

3) Join a club, or tag along on one of their observing sessions. This is the single best piece of advice I can give you. There is no substitute for spending time with real equipment out in the field. You may discover, for example, that you like the portability of Schmidt-Cassegrains, or that you enjoy the views through a good refractor, or that the big Dobsonian you saw in the catalog is much more of a handful than you imagined. Or whatever. There's no substitute for experience.

That said, your ideal first telescope may not be a telescope at all, but a pair of binoculars. Perhaps you have a pair lying around the house already. Most experienced astronomers keep a pair of binoculars close by, for quick peeks or for scanning the field of view before using their telescopes. The common recommendation is to get a pair of 7X50's, or at least, 7X35's. The first number "7" is the magnification, the second "50" is the aperture of each objective lens, in mm. You want the largest lenses you can comfortably hold.

Many astronomers opt for 10X50's, although you should make sure in advance that you can hold them steady at that power. It seems that the current trend is towards 10X50's, but I still like the traditional 7X50 size.
