The Sky-Watcher ED-APO 80mm is a modestly wide-field telescope offering bright, wide swaths of sky in a single view. It is well suited for wide-field astronomical observation of prominent nebulae, star clusters and galaxies from a dark-sky location, or can be used as an astrograph for sky photography. As a terrestrial spotting scope or telephoto lens, the ED-APO's performance is absolutely superb. Ultra high contrast allows the subtlest of details to be easily scrutinized under conditions of good seeing. The petite silhouette of the SW ED-APO 80mm makes for an excellent compact, portable telescope that travels light and fits a small space. At about 50-power structural detail becomes apparent in the solar system's gas giants like Saturn and Jupiter. The Moon also exhibits striking crater detail along the lunar terminator. As an astrograph, the SW PRO 80ED delivers superb performance imaging a wide spectrum of astronomical phenomenon. In a given aperture size, refractors will always exhibit sharper images than other optical designs because the refractor concentrates more light into the central airy-disk and first diffraction rings. There is no diffraction pattern interference caused by a diagonal mirror, or secondary mirror being suspended in the optical path (central obstruction) as is the case with reflectors. Sky-Watcher ED-APO refractor provides the finest images obtainable-bar none-in their design class. Sky-Watcher ED apochromatic refractor delivers dramatic coal-back skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher ED-APO refractor is the logical choice as an investment in advanced instrumentation for exceptional viewing or photography. The Sky-Watcher ED-APO design assures virtual elimination of secondary, residual "false color" normally present in 2-element achromatic lens designs using Crown and Flint glass. Sky-Watcher APO refractors utilize a second lens element made from the mineral fluorite instead of Flint glass. Fluorite, CaF2, is a halide with unique properties and a hardness of only four. It is an exotic and difficult material to fabricate into a lens.FeaturesVirtually Eliminates Residual Chromatic AberrationPride and Perfection in Optical ManufacturingMetallic High-Transmission Lens Coatings: Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put. The proprietary Sky-Watcher "Metallic High-Transmission Coatings" (MHC) are the finest photon anti-rejection coatings in their classLight-Baffled Optical Systems: The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal planePrecision 2" Crayford-style Focuser is Standard: Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Crayford-style rack & pinion focuser-assembly with 1.25" adaptor. Focuser offers 2 speeds for fine and ultra-fine focusing adjustmentsTube Materials: The optical tube material is aluminum, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminum painted white, or blackTelescope Tube Attachment Hardware: The Sky-Watcher APO optical tube comes with attachment hardware that allows them to be securely fastened to the SW EQ5P mountSpecificationsOptical DesignED RefractorLens MaterialFPL-53Aperture (Diameter)80 mm (3.15 in)Focal Length600 mm (24 in)Focal Ratiof/7.5Highest Useful Magnification189xLowest Useful Magnification11 xLimiting Stellar Magnitude12Resolution (Rayleigh)1.74 arc secondsResolution (Dawes)1.45 arc secondsLight Gathering Power131x (Compared to human eye)Finderscope8x50 RA ViewfinderFocuser Diameter2"Optical Tube Length23.8in (605 mm)Optical Tube Weight12.6 lbs (5.72 kg)WarrantySky-Watcher warranty WHO WE ARE Adorama is one of the nation's largest Photographic retail and mail order suppliers.
