Telescopes

Posts Tagged ‘newtonian’

In 1609, Galileo Galilei first looked through his telescope, and changed science forever. His discoveries provided solid evidence that disproved the prevailing belief that the Earth was the center of the Universe. Throughout history, scientists such as Johannes Kepler and Sir Isaac Newton further revolutionized the design of the telescope. To celebrate the International Year of Astronomy, Sky-Watcher is proud to present the commemorative edition of Newton’s Telescope – Heritage.

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 ever 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 as 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.
