Sky-Watcher Evostar-150ED DS-PRO Optical Tube Assembly (10198)

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. The high end Sky-Watcher Evostar-150ED Apo doublet features one Extra Low Dispersion (ED) glass element and a matched crown element. Each air-to-glass objective lens surface has exotic anti-reflection metallic coatings applied, to ensure optimum light throughput of approaching 99.5%. The proprietary Sky-Watcher Metallic High-Transmission Coatings (MHC) are the finest photon anti-rejection coatings in their class. A matching 0.85x Focal Reducer/Corrector is available separately for this product, as well as Deluxe Machined Aluminium Tube Rings and 75mm Dovetail Bar. The Evostar-150ED is supplied without eyepiece, finderscope and star diagonal. Dual speed 11:1 2 inch Crayford focuser. Comes complete with 45mm dovetail mounting bar, tube rings and aluminium carrying case.
