Our beginner's choice: the complete 8-inch Dobsonian!
The Omegon Advanced X 203/1200 is not our standard recommendation for beginners for nothing: 8-inch parabolic mirror, a true Crayford focuser, mirror fan, and an 8×50 finderscope, at a price where others deliver a 6-inch. A Dobsonian consists of two parts: tube and rocker box. Set it down, point it, look. No alignment, no electronics, maximum mirror per euro.
8 inch optics with fan
The 203 mm mirror captures over 800 times more light than the naked eye: galaxies, globular clusters, and nebulae truly come within reach, alongside razor-sharp planetary detail. With the 25 mm Plössl eyepiece, you get 48x magnification; the maximum is around 400x under good conditions. The built-in fan halves the cooldown time of the primary mirror.
Smooth turning, fine focusing
The Teflon bearings with tension springs rotate smoothly in any direction, right up to the zenith. The parabolic primary mirror with 94% enhanced coating extracts merk more light from the same aperture than standard coatings. The 2-inch Crayford tube accommodates heavy wide-angle eyepieces without any play, and the 8×50 finder scope reveals fainter stars than the typical 6×30 model.

Featured accessories
An Omegon Cronus WA 7 mm eyepiece (171x, 79 euros) is the planetary magnification option. The Omegon laser collimator (44.90 euros) comes standard with every Dobsonian. An Omegon 13% moon filter (27.90 euros) reduces the glare of the Moon when viewed through an 8-inch telescope, and the Omegon Pro UHC 2-inch filter (89 euros) brings out the details in nebulae. The Omegon eyepiece holder for Dobsons (16.90 euros) completes the set.
For whom yes, for whom no
Well: everyone who wants to get serious; this is the measure we in the Beginner's Guide advise as the best balance between performance, size, and price. Not: if you are looking for a tabletop model or something portable, then look at the Dobson page to the compact models. More Omegon is on the merk page.
