This Sky-Watcher 90mm (3.54″) f/10 telescope is an achromatic refractor designed for beginners to observe the Moon, planets, and (with a proper solar filter or by solar projection) the Sun, and brighter deep space targets. The low maintenance, enclosed optics come fully collimated from the factory and the refractor makes a good grab and go telescope at . This telescope comes with a 6X30 finderscope, 90° diagonal, 2 eyepieces (25mm and 10mm), and a sturdy alt-azimuth mount (with accessory tray).
Mounting the telescope on the alt-azimuth is quick and simple. The AZ3 mount is a perfect companion for small telescopes and large spotting scopes, with this all-metal alt-azimuth mount being both strong and easy to operate. It features slow-motion control cables on both axes, allowing horizontal and vertical operation.
