Takahashi 1.25" Diagonal Prism
Let's talk quality here. The Takahashi 1.25" star diagonal uses a high quality prism instead of a mirror. This means a lifetime of service where the coatings won't erode. The prism inside the Takahashi star diagonal returns 100% internal reflectivity and what's more, the exit and entry surfaces of the prism are multi-coated for minimum light loss. Don't settle for less.
To protect the barrels of your good eyepieces, Takahashi has designed its star diagonal with a non-marring molded compression ring to hold the eyepiece in place. How many times has a set screw scratched the barrel or become lost in the dark? Not any more. The compression ring is tightened by a ribbed thread-on grip around the eyepiece which simply turns to tighten its hold on your precision cargo. Step up to one of the best!
