Telescopes Buyer's Guide

The Orion SkyView Pro 100ED GoTo Refractor Telescope is a complete equatorial observing package.

When selecting a telescope consider which target objects you plan to explore as well as you level of experience. For viewing most night sky objects, you’ll want a telescope with as much aperture as possible. Keep in mind that as the size of the objective lens or mirror increases, so does the size of the telescope. So, be sure to select a telescope that isn’t too heavy to manage or too complicated for you to set-up. . . especially if portability is a necessity.

More than 400 years ago, Galileo founded modern physics. His discoveries, methods, and creativity provided Isaac Newton with the laws and principles needed for him to discover the laws of gravity. Equally important, he invented and used his telescope to prove our planet is only one part of a sun centered solar system. Galileo records that he designed and built no less than 100 telescopes. But only a handful were good enough to use; efficient enough to bring distant objects 30 times closer.

In 1610 A.D. his finest telescope, the one he used regularly to explore the heavens, provided him with a sharp image only at the center of his lens. Despite fuzziness and “rainbows” surrounding the center image (today called “aberrations”) he was able to explore and understand the celestial wonders his telescope revealed each night. As a result of his explorations, Galileo created an entirely new science . . . Astronomy. Since then, Astronomers have continually strived to perfect the telescope. Indeed, designing and manufacturing telescopes has become a science in and of itself.
