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!

- Questions & Answers
I was wondering whether the Takahashi 1.25" diagonal prism is able to be used with a 13mm Ethos eyepiece? Not sure if the compression ring will be able to be accessed with that particular eyepiece in place. Thanks.Question by: Daniel on Apr 28, 2017 10:31:00 PMGood morning and thanks for asking. I just tried that combination out and you can access the compression ring on the diagonal. Having said that, I did not feel that this was a good combination. The eyepiece was not stable in the diagonal. An eyepiece as large and valuable as the 13 Ethos really needs a 2" diagonal to hold it properly. The Takahashi diagonal is a beautiful piece but the 13 Ethos is too large for it.Answer by: Charles Walker (Admin) on May 11, 2017 12:28:00 PM
