Takahashi 1.25" Diagonal Prism

The 1.25-Inch Diagonal Prism by Takahashi:

 

Takahashi's 1.25-Inch 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-percent internal reflectivity. Its exit and entry surfaces of the prism are multi-coated for minimum light loss. 

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. 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.

Takahashi 1-1/4" Prism Diagonal

Very good product. I like the rotating locking mechanism.

Excellent Prism Diagonal

A very sharp and well-built diagonal. The compression ring doesn't work that well with eyepieces with deep undercuts, but for all others I really like the compression ring. Excellent resolution with little scatter and high contrast. A great diagonal for use with slower telescopes.
