Sky-Watcher 90-degree erecting eyepiece: polar alignment without acrobatics
At our latitude, Polaris is positioned so high that looking through a polar finder quickly leaves you squatting with a strained neck. This 90-degree right-angle viewer solves that: you look into it from above or the side and see the image of the polar finder comfortably in front of you.


The right-angle finder attaches to the polar scope with three thumb screws featuring plastic tips, without scratching. It rotates 360 degrees for the most comfortable viewing angle, offers 1x and 2x magnification, and features diopter correction plus a fold-down rubber eyecup for eyeglass wearers.
