Amateur astronomy is changing into progressively more renowned, normally due to the availability of quite reasonably cheap astronomical telescopes of great caliber - commercially-made Schmidt-Cassegrain and Maksutovs. Rod Mollise's e-book includes every thing novice astronomers want to know approximately those telescopes. that includes (but now not solely) the ever present Meade and Celestron levels, he describes what those tools will do, the way to use them, and that are the easiest to settle on. This ebook comprises every little thing! There are sections on components, looking at innovations, and tricks and advice gleaned from his 25 years event with this kind of telescope: cleansing, collimating, preserving the telescope and mounting; utilizing the telescope in a variety of stipulations; desktop keep watch over; imaging (wet, electronic and CCD). this can be the appropriate e-book for beginner astronomers who're approximately to take a position in a brand new Schmidt-Cassegrain or Maksutov telescope, or if you have already got one and need to get the easiest out of it.

Sample text

They have to do a lot, and their prices have to be kept within the reach of the average advanced amateur astronomer. Because of these facts, there is simply no way they can be expected to be as reliable as, say, a basic-level SCT whose drive consists of a simple battery powered electric motor. If, for any reason, you cannot stand the idea of having your telescope out of service for maintenance, you should probably pass up these most sophisticated and complicated CATs. Many long-time amateur astronomers would also tell you there's another reason for avoiding a goto scope if you're a beginner.

But it also means there's probably a SchmidtCassegrain out there that will be perfect for you, your observing interests, and your budget. A little study and comparison can make buying your first telescope a relatively painless affair. If you're considering buying an SCT or other catadioptric telescope, you need to decide how much you can afford to spend on a new telescope and exactly what you plan to do with it. Price-wise, the seTs have fallen into three groups: introductory bargain scopes, medium-priced models and top-ofthe-line "luxury" CATs.

But what if you just have to have an SCT now, but know you'll want to take photographs and really can't afford one of the more expensive models? If you can't bring yourself to save for just a while longer, one of the introductory GEM mounted scopes may be a good choice. These scopes can often be had with usable German mounts for only a little bit more money than OTA-only SCTs (no mount) command. Once the user is ready to move up to a more sophisticated setup, a topof-the-line GEM can be purchased and the OTA easily switched over.
