Levenhuk Ra 1.25'' star diagonal is a high-quality diagonal mirror that has a reflection angle of 90° and a barrel diameter of 1.25''. The dielectric coating of the mirrors boasts a 99% reflectivity that yields sharp and bright views of observed objects.
Star diagonals are perfect for observations of celestial objects near the zenith with refractors and catadioptric telescopes, as they create an upright, albeit mirrored (left to right), image. The shell of this star diagonal is made of lightweight anodized aluminum. This accessory also comes with a 1.25'' adapter.
