PRODUCT DESCRIPTION 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. 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.
