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, making this OTA suitable for wide field astronomy and terrestrial use.

The high-end Evostar-72ED Apo features a doublet objective lens, with one Extra-Low Dispersion (ED) glass element. Top quality Schott glass is utilised for the Crown element. ED glass is essential for discerning user who demands high performance with low chromatic aberration.

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.
