The Skymax 90's Maksutov-Cassegrain folded optical system provides sharp, high contrast images ideal for observing the Moon, planets, and deep-sky objects. Generally regarded as producing sharper images than Schmidt-Cassegrains, Maksutovs offer astronomers large visual aperture, high contrast and long focal length in a compact package, delivering higher levels of planetary detail due to a focal length that is 5-7 times longer than average Newtonian or refractor telescopes. The Skymax Maksutov-Cassegrains are the ultimate take-anywhere telescopes that, despite their small dimensions, pack a powerful punch with high-resolution, diffraction-limited optical systems that are multi-coated to maximize contrast and image sharpness.
