Optical power, mechanical fluidity and ease of use: this 254 mm Dobson ticks all the boxes!
With a 254 mm parabolic primary mirror, this telescope captures striking detail on even the faintest deep-sky objects, while offering precise planetary images. Its dual-format 1.25″ / 2″ Crayford eyepiece holder ensures precise focusing, even with heavy accessories.
The Dobson mount is based on a simple, robust alt-azimuth principle, popularized in the 70s by John Dobson. The optical tube pivots on two axes thanks to a wooden base, with an adjusted friction system that allows fluid movement by hand while maintaining the chosen position. The result: a telescope quick to set up and pleasant to usewithout complex adjustments.
Unlike spherical mirrors, parabolic mirrors correct the optical aberrations typical of short focal length telescopes. Here, RAQ™ (Radiant™ Aluminum Quartz) treatment ensures up to 94 % reflectivitywith excellent durability over time. The ultra-thin 0.5 mm secondary support reduces diffraction for more punctual stars.
