Hint: Expand your Dobsonian telescope’s capabilities with the Omegon Push+ Go Standalone Encoder System

Now the whole sky consists of nebulae, star clusters and galaxies
The Omegon Advanced X Dobsonian - this is a 'fast' telescope with which you can comfortably observe planets, star clusters, nebulae and galaxies. It is finished to a high-quality, consists of only two sections and is very easy to use. Even if you are a beginner you will have no problems operating it, as it is not neceassry to align the axes. It works on a simple principle - set it up and start observing immediately. But there is even more to it.

The advantages in a nutshell

  • smooth fine focusing - Crayford focuser with 1.25" adapter
  • Teflon bearing and tensioning springs - these let you move the telescope in all directions, up to the zenith or around its own axis
  • main mirror - 94% enhanced coating for brighter images
  • faster cool-down for getting started observing faster - main mirror fan

Main mirror with 94% reflection coating for brighter images
A Dobsonian telescope is an expert in deep sky observing. High contrast, a wealth of visible detail and a bright image go with an excellent telescope just like the stars belong in the night sky - and this is exactly what the parabolic main mirror provides you with. The 94% 'enhanced coating' on the mirror means you can enjoy ultra-bright images, and even lets you make out deep sky objects at the limits of perception.

Get started with your observing faster - main mirror fan
Just a quiet, unobtrusive hum, but with a big effect - the built-in 12V fan means 50% faster cool-down of your main mirror. This allows your telescope to reach optimum image quality more rapidly. So you do not have to wait so long any more.

2" Crayford focuser
Use 1.25" or the larger 2" eyepieces for stunning visual observing. The ball bearings allow you to smoothly focus your objects.

Easy to move in all directions
Move the telescope to view an object and then track it - nothing is simpler! ATeflon bearing on the large azimuth turntable and two tensioning springs on the altitude axis allow you to move your telescope freely in all directions, and to manually track objects to always keep them in the field of view.

The Dobsonian advantage - simple and rapid assembly
What is the advantage of this design? A Dobsonian telescope consists of only two parts, which you can put together in no time. It is also much less expensive than a comparable sized telescope on an equatorial mount. Its main use is for enjoying visual observing. Discover the night sky - it is unbelievable what you can see using your own eyes.
