SKY-WATCHER Dobsonian 8 Inch Dia. w/PARABOLIC MIRROR+*FREE* Star&Planet Locator!

Stores Sky-Watcher 8″ f/5.9 Traditional Dobsonian Telescope with PARABOLIC MIRROR. 8” traditional Dobsonian telescope with smooth Teflon bearings High quality parabolic mirror for clear, sharp imagesPatented Tension Control Handle keeps your telescope where you point it2” Crayford-style focuser with 1.25” adapter for use with either size telescope eyepieces Includes 9×50 finderscope and 2 Plossl eyepieces (10mm and 25mm) Sporting the large light bucket users have come to expect from a Dobsonian, the Sky-Watcher 8″ f/5.9 Traditional Dobsonian Telescope gives users performance at a reasonable price. Its large parabolic primary mirror is highly reflective and corrects spherical aberration to eliminate distortion across the entire field of view, especially at the edges. The four-arm secondary mirror bracket is made with 0.5mm thick fine supports to reduce light loss and diffraction spikes. The large 8″ aperture draws in copious amounts of light to make detailed observations of the Moon and planets, and still reach out past our solar system to discover dim deep-sky subjects. Its f/5.9 focal ratio and Crayford focuser makes this an ideal choice for imaging. Its relatively fast focal ratio enables devices to capture images in less time than slower scopes, while the unique focusing mechanism employed in the Crayford-style gives it the ability to achieve tack-sharp focusing with zero back-lash that rack-and-pinion focusers generally are unable to. This 2″ focuser will accept larger eyepieces so users can enjoy a truly immersive visual experience, and a 1.25″ adapter is included to enable the use of the more common size eyepieces and accessories. Plus **FREE** Rotating Road map of the sky Pinpoint Sky Position Of 500 Stars & 5 Planets 8 1/2″ square chart 16 page Booklet included A must for any stargazer! Pinpoint Sky Position Of 500 Stars & the Planets This road map of the heavens shows the location of the stars, constellations and the 5 naked-eye planets (Mercury, Venus, Mars, Jupiter and Saturn) relative to the horizon for the exact hour and date you determine. Our 8 1/2″ square star chart was plotted by the late astronomer and cartographer George Lovi. The reverse side of the locator is packed with additional data on the planets, meteor showers and bright stars. Included with each star chart is a 16-page, fully-illustrated pocket size instruction booklet. This locator is good now through year 2018!! The heavy base weighs in at 25 pounds and provides a rock-steady platform with very low vibrations. This alt-az rocker mount features Teflon azimuth bearings and a tension clutch on altitude axis. Finally, the tension control handle allows users to adjust the settings allowing them to move the mount easily and smoothly by hand with minimal vibration and maintain its position when released.
