The Zhumell Perigee 100 is one of the most versatile introductory telescopes available. The Maksutov-Cassegrain optical system works well for both viewing and astrophotography. The high grade primary mirror, combined with a premium correcting lens, provides high contrast, low aberration images of both planetary and deep sky objects. The German equitorial mount enables anyone to find and track stars using the built-in R.A. and Dec. scales and included tracking motor. Portable and powerful, the Perigee allows beginning and intermediate astronomers to try their hand at astrophotography with the included Universal T-Adapter. And, if that's not enough, the optical tube can be removed from the equatorial mount and remounted on a photographic tripod for use as a spotting scope. Now that's versatility! A great mix of features for anyone looking to start or add to their telescope collection, the Perigee offers excellent performance at an excellent price.
