Backyard Astronomer's Guide says "...as a low-cost entry into serious viewing, it is unequaled. For a beginner's telescope, this could be the best buy on the market." p.54
NightWatch says, "There may not be a perfect telescope for the beginner, but the closest thing to it is a 6-to-10inch Dobsonian mounted reflector. This type of telescope offers the best combination of modest price, versatility and practicality available in a commercial telescope. For $300 to $700 you get a complete telescope of astonishing capability. It will reveal Cassini's division in Saturn's rings, Jupiter's red spot, the polar caps and dark regions on Mars, thousands of lunar features, the Trapezium at the core of the Orion nebula, hundreds of star clusters in the Hercules cluster and galaxies 60 million light-years away. p. 69
Optional: Solar Filter - will allow you to view sunspots and partial solar eclipses
The Sky-Watcher Dobsonian Telescope (8") 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 models also include the new feature-tension control handle.
WHAT is Dobsonian Telescope?
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 simplicity. In its simplest form, the Dobsonian mount 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.
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 sty 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 stabilization 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.

Recommended: Instructional Videos for assembly and set-up of a Dobsonian. Also, a common error in setting up your Sky-Watcher Dobsonian is to insert the 2" eyepiece barrel into the focuser. Do not use the 2" barrel. You will not be able to achieve focus if you do so. See this instruction and photos for proper set-up for use of the 1.25" eyepieces that come with your Sky-Watcher Dobsonian
