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. • light reflectance: 99%
• mirror performance: 1 / 12?, thickness 12 mm
• aperture: 32 mm
• housing: aluminum + carbon fiber plates (metal body, side covers of carbon fiber)
• angle of deviation: 90 °
• weight: 210 g
