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.



What we recommend
With this telescope you see:
- The Moon in high detail - from crater walls to shadow lines
- Planets such as Jupiter, Saturn and Mars with structures and moons
- Deep-sky objects such as Orion Nebula, Andromeda Nebula and numerous star clusters
- Fainter objects that are simply not visible with smaller telescopes
Not suitable for nature observation or serious astrophotography. Developed as a pure visual telescope for observers who want to push their limits.
