    The Sky-Watcher Black Diamond ED80 is the telescope that heralded in the way of modern imaging. It gave those with a DSLR the perfect OTA for imaging as it allowed for a fully illuminated field in the new wave of APS-C size sensor DSLR cameras. All these years later it is still a great scope for imaging.

    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.

    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 80 ED are cast-aluminium, painted white.
