"Sky-Watchers GoTo Dobsonian
High-tech meets bargain-telescope design. A shotgun marriage or a match made in heaven? We find out!"

"Could the new Sky-Watcher SynScan telescopes really work? ...my doubts were allayed the first night out.Our test telescope,on loan from Pacific Telescope Corp., worked great. Surprisingly so."

- Alan Dyer wrote in his  review of the Sky-Watcher GoTo Dobsonian telescope at SkyNews November/December 2014 issue

Review: Sky-Watcher SynScan GoTo Dobsonian

Sky-Watcher improves on the often unwieldy standard design of Dobsonians with their 14" f/4.9 Collapsible GoTo Dobsonian Telescope. It features a patented truss tube system that enables the front corrector plate/eyepiece assembly to be moved back and locked against the main rear tube to greatly reduce the size of the OTA for storage and transportation. This open OTA also has the benefit of reducing overall weight versus standard Dobs. To add another level of usability to the scope is a motorized ground-based rocker alt-az mount. Equipped with dual servo motors, they are controlled using the SynScan computer hand controller. This self-contained system features over 42,000 celestial objects with alignment assistance, guided tours and full go-to capabilities. Its dual encoders, coupled with the patented Tension Control Handle, enable users to manually move the scope without having to realign it.

It features an exceptionally large 14" aperture conical parabolic mirror to draw in copious amounts of light to make detailed observations of the Moon and planets, and still reach out past our solar system to discover dim deep-sky subjects that smaller scopes are unable to resolve. A conical mirror, as opposed to a standard parabolic, helps to reduce the mirror's weight while allowing it the ability to more evenly acclimate to the ambient temperature. Its f/4.6 focal ratio and two-speed Crayford focuser makes this an ideal choice for imaging. Its fast focal ratio enables devices to capture images in less time than slower scopes, while the unique focusing mechanism employed in the Crayford-style gives it the ability to achieve tack-sharp focusing with zero back-lash that rack-and-pinion focusers generally are unable to.

  • Customer Reviews:


    It arrived in three huge boxes, one containing the OTA, one the 14" mirror and one the parts for the Dobsonian mount. It was easily assembled in about an hour, with the only "sweaty" bit being the mounting of the mirror onto the mirror support in the OTA. This wasn't difficult, just nerve wracking.

    First light was at a reasonably dark sky site and I was simply blown away.

    Get the Dob base horizontal (use a bubble level and some wooden chocks to get this) and the OTA horizontal and pointing North (Home position). Then do a 2 star align. After that the GoTo is accurate to within about 0.3 degrees after a 120 degree slew.

    I can fully resolve M13, right to the core. M57 seems to have colour and the "ring" has structure - it isn't a simple ring.

    Views of lunar craters are simply awesome!

    This 'scope can be used for simple astrophotography of the moon or planets. Long exposures are not possible, but I can (and do) take 100 images of a lunar crater using a Canon 500D, stack and process these, ending up with a pretty pleasing image.

    The mount weighs about 26 kilos and will not go through a doorway. The OTA weighs about 17 kilos. The 'scope can be moved and set up by one person, but it is at the upper limit.

    Overall it is an excellent 'scope, with good optics, awesome light gathering and accurate goto. Tracking is fine for observing, keeping Saturn in the FOV for an hour at x100.

    A good observer's "light bucket", but Dobsonian mount is not suited to more than simple Lunar astrophotography.

    This 'scope is a keeper.
