The dielectric William Optics 1,25 "dome is designed for refractors and telescopes in the Maxutov and Schmidt-Cassegrain constructs, enabling more comfortable observation and restoring the correct vertical orientation (horizontal image is still reversed). Dielectric coatings form a smoother and much more durable surface than aluminum coatings, providing maximum brightness, sharpness and contrast in the image.The efficiency of the reflecting layer is 99% with precision of mirror 1/12 lambda. Fixing the glasses is done by using a clamping ring . The angle cap is made of aluminum alloys, the side covers are made of carbon fiber, and the inside covered with matt to eliminate internal reflections. It also has a 1.25 inch filter thread.
