The razor sharp resolution of Sky-Watcher EQ5P 150AR heroic size refractor will perform on a par with a reflector of up to perhaps 9-inches in diameter on numerous astronomical phenomena. The generous 150mm (6") of light gathering will deliver breathtaking clarity and unrivaled richness of detail in solar system gems, plus vividly express the rich subtle nuisances of intriguing phenomena in deep-space.
This is an eminently manageable large aperture refractor that will become your valued companion for backyard observation and remote excursions to view the primordial sky where bewilderingly rich star fields blanket the firmament. This dream machine will deliver pristine panoramas of massive aggregations of stars forming clusters, brighter galaxies and nebulae contrasted against the deepest-darkest sky imaginable. Sky-Watcher's Crown (BK7) and Flint (F2) achromatic lenses are fabricated to the highest optical standards from Grade-A glass free of striae and other image-degrading imperfections.
Each lens set is individually pitch-polished and hand figured by a highly skilled master optician utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. This ensures diffraction-limited optical performance commensurate with the theoretical resolving limits of the telescope's aperture size. All lenses are uniformly air-spaced. Each optical lens surface is coated with exotic anti-reflection metallic coatings (fully multi-coated) to ensure the optimum light through-put. Four layers are applied to each surface (Magnesium Fluorite, MgF2 and Hafnium Dioxide, HfO2). The proprietary Sky-Watcher "Metallic High-Transmission Coatings" (MHC) are the finest photon anti-rejection coatings in their class.
