The Saxon Dobsonian Telescope 254mm/1200mm (10″) have a “paraboloidal” primary mirror to eliminate spherical aberration and a four-arm, secondary- mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss. In addition, this models include a 2″ focuser with a 1.25″ adapter, allowing the use of either eyepiece size. This model also includes the new feature-tension control handle.
Let’s learn more… So, what is Dobsonian Telescope and why the Tension Control Handle? A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970’s. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its no-frills, ease-of-use. In its simplest form, the Dobsonian mount – such as the one included in the Saxon Dob 10 – consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swiveled on a base in azimuth.
What makes it work? The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not stay where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilisation of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.
The devices for stabilsing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilisation. These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The object of the Saxon Tension Control Handle invention (US Patent No. 6,940,642) is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount. By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.

What can you see with the Saxon Dob 10 – 254mm Reflecting Telescope System? This is a pure astronomy telescope and you’ll be amazed at the incredibly rich deep sky views it provides. Bright star clusters explode like fireworks in the eyepiece and dense star clusters begin to resolve with pin sharp stars. Extended nebula spread across the field of view, showing details like wisps of smoke set against starry skies. Don’t forget the galaxies! Larger, bright galaxies will show details like brilliant core regions and dark dustlanes. Tiny galaxy clusters appear like ghostly grains of rice. Even though the Saxon Dob 10 excels at deep space objects, it is also a fine performer on Solar System objects, too. You’ll be impressed with the deep craters and tall mountains you’ll see on the Moon. Jupiter will reveal its equatorial zones and you’ll see planetary details like the “Great Red Spot” and variations in the cloud tops… and the four Galiean moons will enchant you with their orbits. Saturn will unveil its ring system and you’ll spy Titan and other small moons, too. Mars, when it is close, will have brilliant white polar caps edge by a blue atmospheric haze and will delight you with dark markings like Syrtis Major. Don’t forget the phases of Venus, or the pale coloured orbs of Neptune and Uranus. You can even follow the subtle movements of Pluto or chase asteroids with the Saxon Dob 10!
