Maksutov-Cassegrains are very similar to Schmidt-Cassegrains, but rather they use convex meniscus lenses in replacement of corrector plates. The main advantage here compared to other similar models is that Maksutov-Cassegrains don't need periodic collimation as many other telescopic models do. In addition, because mirror obstruction is smaller, images appear with greater contrasts, but will have a narrower field of view due to the Maksutov-Cassegrain's slow focal ratio which tends to make this telescope design better for planetary and double star observing.
What astronomer wouldn't want a telescope that is "smart"! A telescope that has a brain to memorize the entire sky, wow, it can only be the SkyProdigy 90 from Celestron. Order today!... Learn MoreFREE SHIPPINGModel#: 22091(48 States)
