![]() ![]() Telescopes typically come in two types: equatorial or altazimuth. This one tends to be more versatile, but they do tend to be more expensive than the other types. They are good photographic telescopes and they are a lot easier to carry than the reflector. The catadioptric is a compound telescope, combining both lenses and mirrors.Also, you can't view terrestrial objects with this telescope, because they will appear upside-down. This is one of the better beginner telescopes and it usually has pretty good visibility, although water has a tendency to condense on the optics of the telescope which can be irritating. The reflector employs a large concave mirror rather than a lens for the purposes of accumulating and focusing light. ![]() Unfortunately, it is very hard to see faint objects like galaxies and nebulae. It travels well and doesn't need much maintenance. This one is better for viewing the Moon and planets, usually giving a nice, crisp image. The refractor basically has a long thin tube with an objective lens at the front that collects and focuses the light.Which one you choose will be based on what you want to observe, where you are, and so on. There are really on three basic telescope types: refractor, reflector and catadioptric. Different telescopes are better for different types of viewing. ![]()
