  • Description

    Sky-Watcher’s Skymax 102mm Maksutov-Cassegrain scope offers the same ultra-sharp views you’d get from a 102mm refractor, but without the size, weight, and price tag.

    Versatility meets portability

    The Maksutov-Cassegrain optical design is a favorite for both terrestrial and celestial use. Its correct image optics and high-contrast views make it ideal for use as a spotting scope. With 102mm of aperture, this telescope can easily go from observing deer at long range during the day to viewing the Moon and nebulae at night. But the Maksutov-Cassegrain truly excels when viewing or imaging the planets, thanks to its f/12.7 focal ratio.

    Incredibly, the 102mm Skymax weighs in at under 5 lb. If you need to limit the size and weight of your telescope—whether you’re carrying it on an airplane or taking it camping—this is an excellent option.

    About the Maksutov-Cassegrain

    Although it’s not as widely known as the refractor or Newtonian reflector, the Maksutov-Cassegrain offers superb optical performance. Using a Maksutov corrector lens on the front of the optical tube and a series of mirrors, “Mak-Cass” telescopes correct for visual defects like chromatic aberration and coma. The result is bright images, pinpoint stars, and high contrast views at a fraction of the price of competing designs.
