The exceptionally smart looking Sky-Watcher Black Diamond series ED refractors are made from ED (Extra-low Dispersion) FPL-53 glass precision manufactured in Japan.. This glass greatly minimizes chromatic aberration, provides higher resolution and superior contrast. Colour fringing around objects is virtually eliminated. The refractor also features a backlash-free 2-inch dual speed Crayford focuser. The focuser wheels contain brushed-aluminum hubs with ridged rubber grip rings. These ED refractors are ideal for visual applications as well as astro-photography.

Comes with a variety of useful accessories. See Technical data for details.
