Dobsonian telescopes are among the most practical instruments in astronomy. They are of simple construction and yet a brilliant idea. They essentially consist of two parts: firstly the optics, which in most cases is a solid tube or truss tube design; and secondly the mount, a wooden box (also called a ‘rocker box’) which sits on the ground and into which the telescope is inserted. This design allows you to begin observing sessions immediately without first having to spend time setting up and aligning a complicated mount. The basic idea of the Dobsonian design came from the wish to have a big telescope at a low price, a wish that has succeeded brilliantly. A true fan base has developed since the invention of the Dobsonian telescope which is dedicated to these instruments and their fascinating simplicity and to the idea of ‘high performance at low price’.

The truss tube design allows easy transport of this large telescope in a normal car: the entire instrument can be dismantled into a compact size in just a few easy steps and without the need of special tools.

Some of this 16” Dobsonian’s special features:

  • Premium 406 mm diameter parabolic primary mirror with a fast f/4.5 aperture ratio for exceptional observing experiences!
  • Stable adjustment whereby the primary mirror is aligned without tools using non-slip knurled screws.
  • The cooling fan on the back of the primary mirror enables it to adapt to the surrounding temperature more quickly
  • Adjustable friction brake for the vertical axis so that heavy accessories or eyepieces can be swapped without moving the tube position.
  • Steel roller bearings with two metal plates for horizontal adjustments (azimuth), making delicate tracking possible even at high magnifications.
  • Very good Crayford focuser with 1:10 micro-reduction for precise focusing. Either 1.25” or 2” eyepieces can be used.
  • Comprehensive accessory range for instantaneous success when observing!

It is not only important which telescope you buy, but also where you buy it.
