The highest quality Amici prism giving an uninverted image, the so-called "earthly". The prism is made of perfectly thermally stable Sitall. The innovative BBHS (Broad Band Enhanced Silver) technology was used as the reflective layer, which provides significantly lower surface scattering and much higher contrast than dielectric coatings. Silver in BBHS coatings is hardened and surface protected against oxidation, it also has an extremely wide range of reflectivity, extending from 400 nm to 2 micrometers. The attachment has a 2" mount on the telescope side and a 2" Click Lock adapter on the eyepiece side.
