- Professional customer service If you have any issue about our item, please contact us and we will help you. Tube materials：the optical tube material is rolled steel, powder-coated reflective gloss black with gold fleck accent. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
The draw tube is likewise baffled to insure optimum contrast. The proprietary sky-watcher “metallic High-Transmission Coatings” MHC are the finest photon anti-rejection coatings in their class.
Precision 2” dual speed crayford focuser as standard：optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2” Dual Speed Crayford Focuser-assembly.
The front and back cells are cast-aluminum painted white, or black. Light-baffled optical systems：the objective lens cell is light-baffled to reject stray, unfocused light. This focuser offers fine and ultra-fine focusing adjustments. 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%.
