BLACK DIAMOND 100ED + HEQ5 PRO GPS
Schott Glass Used in Selected Models for Crown Element
Black Diamond ED100 SCHOTT benefit 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.
Observing with Black Diamond ED100 SCHOTT
Fortunate indeed is the amateur astronomer with a Black Diamond ED100mm 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 ED100.

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” Crayford Focuser is Standard
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.
Tube Materials
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 ED100 are cast-aluminum, painted white.
Included Components for Selected Models*
Black Diamond ED100 is supplied with backlash-free 2” Crayford focusers and quality foam-lined metal carrying cases as standard equipment. Black Diamond ED80 is also supplied with 8x50mm viewfinder with bracket; 2” dielectric diagonal; one 28mm LET eyepiece; 1.25” focuser adaptor; and tube ring attachment hardware for mounting to any Sky-Watcher, or other compatible mounts.
The computerized Sky-Watcher PRO mounts are designed with the novice user in mind. With the user-friendly pushbutton SynScan Hand Control, locating and viewing the treasures of the night sky becomes as easy as a walk in the park. The SynScan Hand Control allows you to point the telescope at a specific object or even tour the skies at the touch of a button. The user-friendly menu system allows automatic slewing to over 13,400 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The SynScan Hand Control also has the ability to connect to a computer via a serial cable. Once the connection has been established between the computer and SynScan Hand Control, many commercially available planetarium softwares can be used to control the HEQ5 and EQ6 PRO Mounts, The HEQ5 and EQ6 PRO mounts also comes with features that advanced astronomers can appreciate:
This model includes the GPS receptor, allowing for even more precision and ease of use while aligning and setting up your mount !
Positioning Accuracy up to 1 arc minute. Accuracy enhanced by software collimation error (mount mechanical error) compensation.
Stepper motors with 1.8° step angle and 64 micro steps driven.
