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-R 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-R 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 90° erecting image diagonal provided.
