The Ultimate Light Gatherer

The Dobsonian telescopes are named after John Dobson, an amateur astronomer who designed a very simple but effective telescope, where the key factor is a large aperture for little money. His idea was to mount a Newton telescope on an easy-to-use alt-azimuth mount that does not need time-consuming alignments.

The SkyWatcher 6" Dobsonian is a large aperture Newtonian reflector telescope with f/8 focal ratio, make it ideal for wide field and deep-sky observation. Big aperture means better light gathering power allowing you to see prominent deep-sky object such as nebulae, star cluster and many more. To top it off, the SkyWatcher Classic Dobsonians are equipped with a 2" Crayford focuser with locking screw, to allow easy use of either 1.25" or 2" eyepieces.

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) which adds enough friction and tension to allow the tube to move easily when nudged or to stay solidly in position.
