1.25" star diagonal - 99% reflectivity - 1/12 lambda - CNC metal housing

An excellent 1.25" star diagonal for a very good image - with ring clamp for a secure hold.

Many star diagonals have a reflectivity of approx. 90° reflection (10% light is lost) and have a plastic housing. This 1.25" star diagonal from TS Optics is a really high-quality alternative with excellent imaging and high manufacturing quality. It offers full 1.25" illumination, so long focal length 1.25" eyepieces can also be used. The telescope-side sleeve has a filter thread.

Another advantage over many other star diagonal is the low-set (9 mm compared to 3 to 3.5 mm) clamping screw. The lower position prevents eyepieces with large diameters from blocking the screw.
