Description
Near-zero expansion quartz glass forms the optical core of the Omegon ProDob N 203/1200 DOB II parabolic Newtonian reflector telescope, ensuring swift thermal stabilization under open night skies. Designed in Germany, this 203mm (7.99 inches) aperture Dobsonian features a 1200mm focal length at f/5.9, delivering 0.57 arcsecond Dawes resolving power and reaching magnitude 13.3.
The Omegon ProDob N 203/1200 DOB II incorporates a precision parabolic quartz primary mirror with 94% enhanced reflective multi-layer aluminum coatings. Its roll-formed heavy-gauge steel cylinder shell features cast aluminum cell framework rings, active collimation lock bolts, and a 2-inch dual-speed Crayford focuser. Supported by heavy-duty elevation clutches on a wooden rocker box with needle roller bearings, the complete 20.50 kg (45.19 lbs) system provides silky-smooth manual tracking.
