The Skywatcher Evostar 100ED DS PRO OTA with 0.85x Focal Reducer/Corrector is a great-value package for those looking for a high quality, lightweight 4-inch class ED doublet refractor for both visual and photographic use. This package is extra special value as it comes with not only a 9x50mm straight through finder, aluminium case, 2-inch 28mm LET Eyepiece and 2-inch diagonal, but also a specially-designed 0.85x Focal Reducer and Corrector.

Apochromatic Refractors, due to their unobstructed, text-book like diffraction patterns, produce the sharpest, highest quality optical imaging available, bar-none, aperture for aperture, of any telescope optical system.

These high-end telescopes all feature a doublet objective lens. One element is made from premium Japanese Ohara FPL-53 Extra-Low Dispersion (ED) glass, which virtually eliminates chromatic aberration to deliver true colour reproduction. Top quality Schott glass is utilized for the Crown element.

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.
