Omegon Advanced X N 254/1250 Dobsonian Telescope

Description

Reveal subtle dark lanes across faint planetary nebulae with the Omegon Advanced X N 254/1250 Dobsonian Telescope premium parabolic Newtonian reflector system. Designed in Germany and manufactured in Taiwan, this 254mm (10.00 inches) aperture instrument features a 1250mm focal length at fast f/4.9 speed. The Omegon Advanced X N 254/1250 delivers 0.46 arcsecond Dawes resolving power and reaches magnitude 13.8.

The Omegon Advanced X N 254/1250 Dobsonian Telescope features a premium low-expansion parabolic glass mirror with enhanced multi-layer aluminum coatings achieving 94% reflectivity. Its roll-formed heavy-gauge steel cylinder shell incorporates cast aluminum cell rings, active collimation lock bolts, and a battery-powered primary mirror cooling fan. Supported by heavy-duty altitude rollers and a wooden rocker box, the complete 27.70 kg (61.07 lbs) system maintains exceptional mechanical rigidity, while the optical tube weighs 14.50 kg.

Enhanced 94% Reflective 10-Inch Parabolic Optics

The 254mm low-expansion parabolic primary mirror maximizes photon collection across an expansive optical surface. Featuring active collimation lock bolts and a 2-inch Crayford focuser, this Omegon Advanced X Dobsonian supports clear visual observations from 36x up to 500x magnification.

Primary Mirror Cooling Fan & Heavy-Duty Altitude Bearings

Rapid thermal equalization is essential when observing deep-sky targets under dropping night temperatures. The Omegon Advanced X N 254/1250 includes a battery-powered primary cooling fan that clears tube currents quickly. Supported by heavy-duty altitude side-boss rollers, this Dobsonian glides smoothly across the wooden rocker box cradle for precise manual tracking.

• Battery-powered cooling fan attached to the primary mirror cell for fast equilibrium
• Heavy-duty altitude roller flanges resting in low-friction rocker box channels
• Included 2-inch Erfle 30mm ultra-wide eyepiece delivering expansive rich-field views
