Sky-Watcher EVOSTAR-150mm F8 ED DS-PRO (OTA
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 Evostar-150ED Apo doublet features an undisclosed combination of 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 will be available separately for this product.
