Are these good? Yes! These prism diagonals have excellent reflectivity! Our customers love these. We are confident you will too.
Why use a prism diagonal over a mirror diagonal? Prism diagonals are preferred for slower focal ratios (f/6+) – Prisms have a shorter optical path, meaning that if you can’t rake out the focuser in enough to reach focus, a prism diagonal may help.
