Rich-Field 4.5 Inch Newtonian Reflector Telescope. Possibly the best reflector telescope value available today, this 4.5" scope boasts a short 500mm focal length. As a result, this scope packs a super-fast F/4.4 F-ratio, making it an extremely powerful instrument for wide-field and deep space astronomy. With its tremendous light-gathering power, you can observe fabulous nebulae, galaxies, binary star systems and most of the famed deep space Messier objects in dark skies. You can see outstanding detail when viewing the moon you'll spot the Rings of Saturn and the Moons of Jupiter. Included is an adjustable full-sized aluminum tripod with a built-in accessory tray. This scope has an Equatorial Mount, so it can be polar aligned to track the movements of stars parade across the night sky. Use the declination circle, hour circle and latitude scale to quickly locate any celestial body. Thanks to precision worm gears and a substantial counter weight, the telescope can be balanced so that the slightest finger touch turn of the flexi cables will move the telescope with a smooth, steady motion. An optional right-ascension motor drive is available. Two medium power 1.25" diameter Plossl eyepieces (25mm & 10mm) and a Barlow 2x lens are included. Additional 1.25" eyepieces are available. Also included is a dust-free cleaning cloth, a map of the surface of the moon and a moon filter designed for reducing moon glare, and a poster of the solar system. The primary mirror is collimated (aligned) at the factory, but the scope does not include collimation aides, tools or instructions. All reflector telescopes show an inverted image, so purchase an optional erector eyepiece for daytime terrestrial viewing. Because the included paper instructions offer limited guidance, we provide buyers with an online full-color photograph, step-by-step assembly guide so you'll be up and running without having to struggle with a complex assembly diagram.
