Baader Planetarium 2 Inch 90 Degree Erecting Prism Diagonal

Description

Baader Planetarium produces what we think is easily the finest amici prism star diagonal available today.  The prism has been made to the proper specifications, in order to provide image quality that suffers from none of the defects found in commonly available correct image amici diagonals.  The finest 7-Layer Multi-Coatings ensure the image is bright and contrasty, and the oversized prism provides the full clear aperture of 1.25”!  The precision machined aluminum housing provides a stress free mounting and precise location for the prism, unlike the typical weak plastic or crudely cast and machined housings found on lesser diagonals.  The end result is a correct image diagonal that is good enough for more than just high-quality terrestrial viewing.
