About this product

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 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″ rack and pinion focuser and focuser locking screw – to allow easy use of either eyepiece size.

Optics with 94% Reflectivity

All Dobsonians utilize a borosilicate mirror with a quartz overcoat, producing an incredible 94% reflectivity rating!

Complete with Accessories

Comes complete with a finderscope, two 1.25-inch eyepieces (10mm and 25mm), and a 2-inch to 1.25-inch adapter.

Patented Tension Control Handle

Using Sky-Watcher's patented tension control handle provides the Classic Dobsonian with solid control for precise aiming and slewing.

Separates Into Two Sections

Sky-Watcher's Classic Dobsonian is easy to transport and quick to setup. Simply set the optical tube into the base and thread on the tension knob.

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.
