If you’re seeking crisp, contrasty views with high levels of detail, look no further than the Skymax series, Sky-Watcher’s premiere line of Maksutov-Cassegrains. Generally regarded as producing a sharper image than Schmidt-Cassegrains, Maksutovs offer astronomers a large visual aperture, high contrast and long focal length in a compact package. These telescopes deliver higher levels of planetary detail due to a focal length that is 5-7 times longer than your average Newtonian or refractor telescope.

Skymax Maksutovs feature mirrors constructed of borosilicate, polished and coated with our proprietary Radiant Aluminum Quartz™ (RAQ™) coatings, which produce a remarkable 94% reflectivity. All Maksutovs use a corrector plate to help reduce chromatic aberration, which is then coated using our signature Metallic High-Transmission Coatings (MHTC), producing professional grade optics at an affordable price. 

The Skymax 90 includes two 1.25-inch eyepieces, red dot finder, 1.25-inch diagonal, ¼-20 mounting plate, and a soft carrying case.
