Omegon Dobson Telescope Advanced X N 254\/1250 is a 10-inch Dobson that takes visual observation to the next level. With a mirror aperture of 254 mm, this telescope captures over 2.5 times more light than a 150 mm model. This means that faint deep-sky objects such as spiral arms of galaxies, nebular structures and compact clusters become much more visible.

The stable wood Dobson mount provides intuitive operation. With Teflon bearings and sturdy construction, move the tube smoothly without vibration. The Crayford focuser allows accurate focusing even at high magnifications. A fan under the main mirror speeds up cooling, so you get a stable image faster. Smart balance mechanism keeps the telescope stable in any position, even when using heavier eyepieces.<\/strong><\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n

What we recommend<\/strong>
With this telescope you see:<\/p>\n\n\n\n

    \n
  • The Moon in high detail - from crater walls to shadow lines<\/li>\n\n\n\n
  • Planets such as Jupiter, Saturn and Mars with structures and moons<\/li>\n\n\n\n
  • Deep-sky objects such as Orion Nebula, Andromeda Nebula and numerous star clusters<\/li>\n\n\n\n
  • Fainter objects that are simply not visible with smaller telescopes<\/li>\n<\/ul>\n\n\n\n

    Not suitable for nature observation or serious astrophotography. Developed as a pure visual telescope for observers who want to push their limits.<\/p>\n\n\n\n
