10-inch light output: deep-sky gets serious!<\/strong><\/h2>\n\n\n\n

The Omegon Advanced X 254\/1250 is the step at which deep-sky truly begins. The 10-inch mirror collects about 1300 times more light than the naked eye: globular clusters break apart into stars, and spiral structure in bright galaxies comes within reach. A Dobsonian consists of two parts: tube and rockerbox. Set up, point, observe. No alignment, no electronics, maximum mirror for your money.<\/p>\n\n\n\n

10-inch optics with fan<\/h4>\n\n\n\n

With the 25mm Pl\u00f6ssl eyepiece, you get a 50x magnification with a wide field of view. The theoretical maximum is above 500x; in practice, the atmosphere limits it to around 300x to 350x. The f\/4.9 optics require precise collimation; the built-in fan quickly brings the mirror up to temperature.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Smooth turning, fine focusing<\/h3>\n\n\n\n

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 merkbar more light from the same aperture than standard coatings. The 2-inch Crayford tube accommodates heavy wide-angle eyepieces, which this aperture requires.<\/p>\n\n\n\n
