BLACK DIAMOND - ED SERIES REFRACTORS
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. these breathtakingly pristine celestial views are coveted by experienced amateur astronomers. While the cost is expensive compared to a Newtonian reflector of similar aperture, during those cherished moments of transparent and stable air, the aprochromatic refractor delivers the closest experience to being there human beings may eve know.
What is the most faithful imaging known to amateur astronomy worth? At some point, if you stay serious about the hobby, you too will come to the same realization of thousands of others before you that the APO experience, if not priceless, is indeed at least worth the cost of admission. Sky-Watcher is a leader in the design and manufacturer of ED-APO systems.
