  • The Sky-Watcher Skymax 180mm Maksutov Cassegrain Optical Tube Assembly is a remarkable choice for planetary observation.
  • The Maksutov cassegrain design and slow focal ratio give impressive views and details of planets that are normally harder to obtain with newtonians and refractors.
  • Borosilicate mirrors and RAQ coatings result in 94% reflectivity.
  • Metallic High-Transmission Coatings reduce chromatic aberration so views are sharp and clean.
  • Includes a 2" 28mm eyepiece, 9x50 finderscope, 2" diagonal and V-style dovetail

Sky-Watcher Skymax 180mm Maksutov-Cassegrain Optical Tube Assembly

For observers who enjoy viewing the planets in fine detail, the Sky-Watcher Skymax 180mm Maksutov-Cassegrain Optical Tube Assembly is the perfect choice due to its Maksutov design which in general excel at terrestrial and planetary observation due to their slow focal ratio and focal lengths which are 5-7 times longer than Newtonians or refractors. In addition, the borosilicate mirrors of the optical tube are coated with Sky-Watcher's Radiant Aluminum Quartz (RAQ) which produce 94% reflectivity. On top of that, chromatic aberration and false color is significantly reduced with the corrector plate that is coated with Metallic High-Transmission Coatings.

Included items consist of a 2" 28mm eyepiece, 9x50 finderscope, V style dovetail and 2" diagonal
