The Ultimate Light Gatherer

The Sky-Watcher 10″ Dobsonian is a large aperture Newtonian reflector telescope with f/5 focal ratio, make it ideal for wide field and deep-sky observation. Big aperture means better light gathering power and with this Sky-Watcher Telescope you are able to see prominent deep-sky object such as nebulae, star cluster and many more. To top it off, the Sky-Watcher Classic Dobsonians are equipped with a 2″ Crayford focuser and focuser locking screw –  to allow easy use of either eyepiece size.


Tension Control System
The Tension Control System allows you to adjust the friction setting; to increase or reduce the amount of resistance when moving the tube on the wooden mount, so you always have the appropriate resistance. The secret of the design is to correctly balance the optical tube with the specially designed handles (found on the base) and this adds enough friction and tension to allow the tube to move easily when nudged or to stay solidly in position.
