DESCRIPTION

Sky-Watcher 90mm Maksutov-Cassegrain Telescope OTA

This Sky-Watcher 90 mm Maksutov-Cassegrain Telescope is the ultimate portable scope with impressive performance. You could take it anywhere. Although this telescope is small in size, it has optical quality beyond what you might expect from a smaller scope. Because it uses the diffraction-limited Maksutov optical system, it produces high resolution sharp images with high contrast. The optical elements are fully multi-coated to further enhance the image contrast.

With this 90 mm Maksutov Cassegrain Telescope by Sky-Watcher, focusing is accomplished by turning a knob on the rear housing of the scope, which moves the primary mirror slightly to adjust focus. Focusing is smooth and precise.

The Sky-Watcher 90 mm Maksutov Cassegrain Telescope comes with a 1.25" 90 degree Star Diagonal to make viewing more comfortable, as well as a 25mm and a 10 mm Plossl eyepiece and a Red Dot Finder to make finding celestial objects supere easy. If you are a beginner in the facinating and fun hobby of astronomy, this telescope is a good way to start enjoying impressive views of all those objects you want to see.
