Sky-Watcher 90/900 AZ3 Refractor Telescope

The Sky-Watcher 90/900 Refractor telescope is a two-element, air-spaced, fully multi-coated objective, achromatic refractor. It allows you to view detailed vistas of star fields, clusters, nebulae, planets and other celestial bodies. It makes a fine terrestrial telescope when mounted on an alt-azimuth mount.

Premium Astronomy and Terrestrial Observation

Sky-Watcher 90/900 refractor telescope is a well proven performer in value for views of comets, star fields, star clusters, planets, bright galaxies & nebulae, the Moon and the Sun (with proper safety filtering!). Supplied with the sturdy and easy to use AZ3 alt-azimuth mount, which provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes, this Sky-Watcher 90/900 AZ3 refractor is also used as a daytime terrestrial telescope.

The Refractor Advantage

Since a refractor does not use mirrors to view objects, you get a generally sharper image. Images are also displayed without the secondary mirror shadow, making it suitable for terrestrial viewing when used with  45° erecting image diagonal provided.

High Quality Imaging

This achromatic refractor from Sky-Watcher features an aperture of 90mm and it is fully multi-coated to enhance light transmission. It delivers clear, high contrast images of the Moon and the planets. Those new to astronomy will appreciate how simple and easy this telescope is to use.
