Are these good?  Yes!  These prism diagonals are made to exacting standards.  Our customers love these.  We are confident you will too.

Why use a prism diagonal over a mirror diagonal?  While mirror diagonals are preferred for faster focal ratios, prisms work very well with longer focal length classic telescopes.  The prism version also has a shorter optical path, meaning that if you can’t push in the focuser far enough to reach focus, this prism diagonal may help.
