Quick Overview

SkyWatcher 90° 50,8mm dielectric diagonal mirror has a high quality dielectric mirror (with a better reflectivity than standard mirror diagonals) with a great price! When you point a telescope with back focus (like a refractor or a Schmidt-Cassegrain) toward the zenith (ie vertically), the eyepiece is in a very awkward position. For this reason, before the eyepiece, a mirror diagonal is inserted into the focuser which put the eyepiece in a more comfortable viewing position. But if the mirror diagonal hasn't high quality, you will loose contrast and brightness in images given by your telescope.... SkyWatcher 90° 50,8mm dielectric diagonal comes also with 31,8mm reducer.
