Klappentext The Meade ETX range of telescopes is one of the most successful ever made. It is low-cost! has sold in its tens of thousands! and is available in almost every country. Here! ETX expert Mike Weasner reveals everything any amateur astronomer ever wanted to know about the telescope. First book dedicated entirely to the ETX. Written by an acknowledged world authority. Describes the "best" 100 objects to begin observing. Contains detailed hints and tips aimed at getting the best out of the ETX. Features imaging (photographic and digital) as well as visual observing.
