Skywatcher ED120 Black Diamond



The larger aperture of the Skywatcher ED120 Black Diamond telescope renders a remarkable increase in resolution and a improved sense of observing lunar and planetary surface phenomenon in seemingly 3D-like high definition.

Tight globular star clusters like M13 in Constellation Hercules appear like a beehive of crisp stellar pin points, star upon thousands of stars deep into the objects core.

In Deep-space, rich aggregates of stars within Galaxies, Nebulas, and open clusters appear brilliant contrasted against a very dark velvet black background.

The wispy, delicate, featherlike structure of dust lanes and extension of glowing gasses can be seen reaching out far beyond the object’s core.

Metallic High-Transmission Lens Coatings

Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put of approaching 99.5%. The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class.

Light-Baffled Optical Systems

The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.

Precision 2” Crayford Focuser is Standard

Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2” Crayford rack and pinion focuser-assembly. This focuser offers fine and ultra-fine focusing adjustments.
