Observing with Black Diamond 120 ED<\/strong>
\nFortunate indeed is the amateur astronomer with a Black Diamond 120 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 \u2013 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 120 ED.<\/p>\n

Metallic High-Transmission Lens Coatings\u00a0<\/strong>
\nEach 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 \u201cMetallic High-Transmission Coatings\u201d (MHC) are the finest photon anti-rejection coatings in their class.<\/p>\n

 <\/p>\n

Light-Baffled Optical Systems<\/strong>
\nThe 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.<\/p>\n

 <\/p>\n

Precision 2\u201d Dual Speed Crayford Focuser is Standard<\/strong>
\nOptical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision\u00a02\u201d Dual Speed Crayford Focuser-assembly. This focuser offers fine and ultra-fine focusing adjustments.<\/p>\n

 <\/p>\n

Tube Materials<\/strong>
\nThe optical tube material is rolled steel, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminium painted white, or black.<\/p>\n

 <\/p>\n

Telescope Tube Attachment Hardware<\/strong>:
\nThe 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 120 ED are cast-aluminium, painted white.<\/p>\n

 <\/p>\n

Included Components for Selected Models*<\/strong>
\nBlack Diamond 120 ED is supplied with backlash-free 2\u201d Dual Speed Crayford Focusers and quality foam-lined Aluminium carrying cases as standard equipment.<\/p>\n","protected":false},"excerpt":{"rendered":"
