Sky-Watcher Evostar 100 ED APO Refractor Telescope

DESCRIPTION

Sky-Watcher Evostar 100 ED APO Refractor Telescope

The Sky Watcher Evostar ED100 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 Skywatcher ED100'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 Sky Watcher Evostar ED100 makes for an excellent compact, portable telescope that travels light and fits a small space.

Fortunate indeed is the amateur astronomer with a Sky-Watcher Evostar ED100mm refractor on a clear night with transparent skies and a stable atmosphere. It's the "Black Diamond" of the optic world. Turning the telescope to the Crescent Moon, the Apennine Mountains snap into razor-sharp focus revealing a cornucopia of jagged mountain ridges, canyons, and numerous small craters in ultra high definition. 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. Prominent deep-space nebula yield improved definition in gaseous outer extensions. Stars in globular clusters resolve to pinpoints. This is just the beginning of an incredible journey of exploration possible with a Pro ED100.

The Sky Watcher Pro ED100 benefits from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation, and famous-brand camera lenses. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers. Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put of approaching 99.5%. The proprietary Sky-Watcher Metallic High-Transmission Coatings (MHC) are the finest photon anti-rejection coatings in their class.

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. Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Crayford rack & pinion focuser-assembly. This focuser offers fine and ultra-fine focusing adjustments. The optical tube material is rolled steel, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminum painted white, or black.

The optical tube comes with attachment hardware that allows it to be securely fastened to any Sky-Watcher mount. The quick-release tube rings provided with SkyWatcher Pro ED100 are cast-aluminum, painted white. The ED100 is supplied with backlash-free 2" Crayford focusers and quality foam-lined metal carrying cases as standard equipment. Black Diamond ED100 is also supplied with 8x50mm viewfinder with bracket; 2" 1.25" focuser adaptor; and tube ring attachment hardware for mounting to any Sky-Watcher, or other compatible mounts.
