The unique collapsible (telescoping) design of this big 16" Sky-Watcher go-to collapsible Dob sets new standards for transportability and ease of set-up and take-down. Even better, it will find and track over 42,000 celestial objects for you at the touch of a button or two.

This 16" Sky-Watcher go-to collapsible truss-tube Dobsonian has:
  • 16" (406 mm) Dobsonian-style Newtonian optics
  • built-in WiFi telescope control
  • conical primary mirror for faster cool-down
  • 1800 mm focal length (f/4.4)
  • 2" dual-speed Crayford-style focuser with 1.25" adaptor
  • 25mm and 10mm 1.25" 4-element Plössl eyepieces
  • 8x50 RA erect-image finderscope
  • SynScan hand controller with 42,000 object database
  • Go-to Dobsonian base with DC servo motors and dual encoders

The 16" Sky-Watcher Dobsonian SynScan is a precision engineered large aperture go-to "light bucket" telescope that lets you easily find and enjoy viewing over 42,000 deep sky treasures - the Moon, planets, nebulas, star clusters, multiple star systems, galaxies, and more. Despite its very large aperture, its patented collapsible tube design lets you set up this big 16" Dobsonian in minutes in your back yard as well as fit into virtually any car for transporting to a dark sky observing site. It is truly the ultimate in portability and performance in a scope of such substantial aperture.

The collapsible truss tube design combines ease of use, extreme portability, and consistent big-scope performance in an affordable package. Unlike other truss tube designs, the 16" Sky-Watcher collapsible Dobsonian does not need to be completely disassembled into multiple components when not in use. There is no need to struggle with a collection of truss tubes that have to be packed and reassembled separately.

The secondary mirror cage with its attached trusses slides down onto the mirror box, allowing all the optics to be lifted out of the scope base as a single unit with the trusses attached. The two assemblies (optics and base) can then be transported separately and reassembled and ready to use in just minutes.

The 16" Sky-Watcher Dob is easy to collimate once set up, and it holds its collimation throughout the evening! Its patented tension control handle allows you to add or reduce tension in altitude when changing eyepieces, to compensate for the added weight of today's massive wide field eyepieces.

The Sky-Watcher SynScan™ AZ hand control allows you point your telescope at a specific object, or even tour the best objects visible in the night sky, at the touch of a button. The user-friendly menu system allows automatic slewing to over 42,900+ objects. Even if you have never used a telescope before, you can master its variety of features in only a few observing sessions. The patented dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need to re-align on the sky after you have moved the scope.

The 16" Sky-Watcher Dobsonian SynScan combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized go-to telescope that takes the work out of finding your way around the sky.
