      Sky-Watcher Dobsonian Telescopes are a popular choice for amateur astronomers.  You get a large aperture sizes at affordable prices and it is one of the most practical optical instruments in world of astronomy.
      Designed to be simple, Sky-Watcher Dobsonian consists of 2 parts: a solid tube and a wooden mount and almost immediately will allow you to start your observation sessions without spending time on setup.

      The Sky-Watcher 10" Dobsonian Telescope  254mm/1200mm (10") has 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 model includes 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. Its large aperture size of 10 inches offers you a greater view of fainter celestial objects, greatly improving your viewing experience!

      Pyrex Glass Optics

      The Sky-Watcher 10” Dobsonian features a primary mirror made of Pyrex glass. Because of its very low coefficient of thermal expansion, Pyrex glass is less affected by changing temperatures. This greatly reduces the cooling time of a telescope larger than 8” in diameter without using an extra fan. The great stability of this low expansion glass ensures high quality images. It is also substantially more resistant to scratching then plate glass. Available on 254mm/120mm (10") only

      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 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.

      The devices for stabilizing 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 stabilization. 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 Sky-Watcher 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.

      Sky-Watcher Smart Phone Adapter 

      The Sky-Watcher Smart Phone adaptor is the easiest way to start your journey into astrophotography.

      It works by clamping onto you telescope eyepiece and positioning your iPhone or Android phone securely over the eyepiece.  You can use your standard phone camera app or one of the growing number of astronomy related camera apps for both iOS and Android.

      Even with the most basic smart phones, you’ll be able to capture stunning photos of craters and features on the Moon and with higher end phones, images of stars, nebula and planets can be captured as well.

      • Connect your smart phone to your telescope eyepiece.
      • Fits phones up to 100mm wide.

      Recommended Usage - Viewing Galaxies/Stars, Viewing Nebulae, Viewing the Moon and other planets

      Excellent Service and Telescope

      I’m a newbie and didn’t really know where to start. Terrie helped me select a telescope that fit within the perimeters I had set. I’ve used it a handful of times now and not had one single issue! It is perfect for what I am using it for. Already had a good view of the Moon, Jupiter and seen the rings around Saturn. All crystal clear! Highly recommend!

      Great telescope

      Unfortunately we bought this telescope when the weather just turned into long rain and clouds, so took a while till we could actually use it. By that time all what was available to observe- deep space, my teenage son was amazed by the amount of stars you can see even when the sky looks empty and the bright stars are either double or the galaxies(while no you don`t see galaxies the way they are shown by NASA or astronomers-there is no colourful clouds, you can see grey shadows in different shapes). Last night we finally had a first look at the moon and while didn`t see footprints or American flag or moon rovers, the details of craters and seas were amazing. Anything what can pull my teenagers from their phones is a big win in my family and this telescope did that

      Operation issues

      He loves it, but having trouble getting it to focus on the moon etc…. Any suggestions would be appreciated.
