- Sky-Watcher 100/900 Black Diamond ED Doublet Refractor Telescope
The wide Sky-Watcher 100/900 Black Diamond ED Doublet Refractor Telescope is perfect for Planetary and Deep-Sky observations as well as CCD imaging and widefield astrophotography. It has a proprietaryMetallic High-Transmission Coatings, which are the finest photon anti-rejection coatings in their class. Featuring 100mm Diameter and 900mm Focal Length, you’ll get the right amount of light and wide field of view. With light-baffled optical systems, it is capable of rejecting the stray, unfocused light. In addition to its optical tube, the material is made to be a rolled steel, powder-coated reflective gloss black with gold fleck accent.
Product Features in Detail
Observing with Black Diamond 100 ED
Fortunate indeed is the amateur astronomer with a Black Diamond 100 ED refractor on a clear night with transparent skies and a stable atmosphere. 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 Black Diamond 100 ED.
Metallic High-Transmission Lens Coatings
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.
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” Dual Speed Crayford Focuser is Standard
Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2” Dual Speed Crayford 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.
Telescope Tube Attachment Hardware
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 Black Diamond 80 ED are cast-aluminium, painted white.
Included Components for Selected Models
Black Diamond 100 ED is supplied with 2” Dual Speed Crayford Focusers and quality foam-lined aluminium carrying cases as standard equipment.
