Description
Combining an 8-inch collapsible optical tube with motorized SynScan GoTo tracking, the Skywatcher Dobson N 203/1200 Skyliner FlexTube BD DOB GoTo computerized telescope delivers 0.57 arcseconds Dawes resolving power. Built with a 203mm (7.99 in) aperture, a 1200mm focal length, and an f/5.9 focal ratio, this system reaches magnitude 14.2 for automated deep-sky exploration and lunar observation.
The Skywatcher Dobson N 203/1200 Skyliner FlexTube BD DOB GoTo features a parabolic borosilicate primary mirror with 94% reflective aluminum coatings and a protective silicon dioxide overcoat. Its collapsible truss-tube assembly collapses to 830mm for vehicle transport. Mounted on a computerized SynScan GoTo Dobsonian base with DC servo motors and Freedom-Find dual encoders, the 11.00 kg (24.25 lbs) OTA tracks celestial objects automatically without losing manual positioning coordinates.
Key Features of Skywatcher Dobson N 203/1200 Skyliner FlexTube BD DOB GoTo
Engineered for automated celestial GoTo tracking and visual deep-sky exploration, this 8-inch Sky-Watcher FlexTube Dobsonian pairs a collapsible optical tube with a computerized SynScan base. Its Freedom-Find dual encoders and DC servo motors deliver silent, high-accuracy pointing across thousands of night sky targets.
