DESC: Nearly 400 years ago, a German mathematician enabled us to view our solar system better than we ever had before. By recognizing that planets moved in an elliptical orbit and developing an optical system on which today's refractor telescopes are still based, Kepler allowed generations of astronomers to closely study the planets of our solar system. Building upon the tradition he began, the Zhumell Kepler invites you to discover the wonders which exist beyond our world. The 6" objective lens gives you the light gathering capabilities needed to study a wide range of celestial objects. The 1200mm focal length provides the magnification needed for close-up study of lunar features. The refractor design is perfect for viewing Mercury, Venus, Mars, Jupiter and Saturn clearly. Resolving power of 0.76 arc seconds allows you to split binary systems. Achromatic, fully multi-coated lenses allow accurate color transmission and maximum light transmittance.
