Sky-Watcher Equinox 80 ED Apochromatic Refractor OTA
Sky-Watcher Equinox Series is the high end of the affordably priced family of apochromatic refractors. They feature the same precision optics as the ED Refractor Series but are housed in tube assemblies of the highest mechanical quality with unique features.FPL-53 ED GlassExtra-low Dispersion glass allows the optical designer to virtually eliminate chromatic aberration (false color fringing around bright objects). This results in higher resolution and superior contrast in the images. This premium glass choice is a basic warranty for virtually no false color and for high contrast.Schott Glass Used in Selected Models for Crown ElementThe Equinox Series benefits from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems including medical instrumentation and famous-brand camera lenses.Metallic High-Transmission Lens CoatingsEach air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put of approaching 99.5% The propietary Sky-Watcher Metallic High Transmission Coatings (MHC) are the finest photon anti-rejection coatings in their class.Other FeaturesRetractable dewshield with aluminum dewshield capL-shape bracket for easy mounting on any camera tripodExtra-Smooth and precise Crayford focuser provides reliable two-speed focusingGraduated scale on the drawtube for fast and precise focusingSkyWatcher Equinox 80mm OTAThe Equinox 80 is another excellent choice for birding nature study and photography. Its fast high-contrast optics and generous field of view make it an ideal instrument for studying larger clusters and star fields and it is a proven performer for astrophotography – you can even use it with a common SCT focal reducer to achieve speeds down to f/4.5! But don’t be afraid to push up the magnification too. Its crisp optics make it a strong performer on tight double stars and it provides crisp clear lunar and planetary images with no image breakdown even at 150x.Schott Glass Used in Selected Models for Crown Element Equinox 80 benefit from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems including medical instrumentation and famous-brand camera lenses. While Schott glass is only used in selected models all other models utilize top-quality Grade-A glass from perhaps less famous but nonetheless highly respected high-quality glass manufacturersMetallic 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%.
