The Sky-Watcher Pro SW 100ED APO 100mm ED Refractor Telescope is manufactured using only the finest fabrication materials available for painstakingly rigorous, exacting standards of optical and mechanical quality to insure the amateur astronomer peak performance and a great experience each and every time a Sky-Watcher ED-APO is taken into the field. Turning the telescope to the first quarter Moon, the Apennine Mountains snap into focus revealing a cornucopia of jagged mountain ridges, canyons and numerous small craters in razor-sharp detail.

Not far removed, reaching skyward the crater wall of Archimedes pops into view in bold relief against the smooth flatlands that transverse the distance between it and the Apennine Mountains. This is lunar observing at its best - HD style. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons and tonality within the bands. The great spot is clearly visible, discreetly contrasted from the surrounding Jovian landscape. Saturn's storied surface phenomenon is simply stunning. Hunt down double stars like Epsilon Lyrae, the "double-double" in Lyra. A 100mm refractor will provide a crisp well defined image superior to even a larger reflector.

Always a star-party favorite, Alberio located in the tail of Cygnus never fails to please as it is a beautiful double. Alberio appears like a gold sparkler and its companion looks blue-green. It is a perfect refractor object. Compact globular star clusters lend themselves well to a refractor. Located outside our galaxy the globular M2 will probably resolve more stars in a 4" refractor than a 6" reflector. M4, M10 and many other globular cluster can be seen well with a 100mm refractor. M13, the fantastic globular in Hercules is a stunning sight in a 100mm refractor.

The bright central cores of prominent nebulae can be seen and the brightest stars can be resolved. As an astrograph, the SW PRO 120ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space 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.

Sky-Watcher 100ED Refractor Features

  • Virtually Eliminates Residual Chromatic Aberration
  • Pride and Perfection in Optical Manufacturing
  • Metallic 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 class
  • Light-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 plane
  • Precision 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. This focuser operates at 2 speeds for fine and ultra-fine focusing adjustments
  • Tube Materials: The optical tube material is aluminum, powder-coated reflective gloss black with gold fleck accent
  • Telescope Tube Attachment Hardware: The Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to the SW EQ5P mount. The quick-release tube rings provided with SW ED-APO models 80ED 100ED and 120ED are cast-aluminum, painted white
