Description

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.

Quick Overview

  • Maksutov-Cassegrain optical design
  • Primary and secondary mirrors feature proprietary Radiant™ Aluminum Quartz™ (RAQ™) coatings
  • Corrector plate featuring Metallic High-Transmission Coatings™ (MHTC™) virtually eliminates chromatic aberrations
  • 90mm aperture, 1250mm focal length, f/13.8 focal ratio
  • Aluminum tube coated with glossy, black diamond metal-flake finish
  • Included accessories: two 1.25-inch eyepieces, red dot finder, 1.25-inch diagonal, ¼-20 mounting plate, and a soft carrying case
