1,25" 45-graden oprichtprisma (D1032)

The compression ring on this 1.25" erecting prism holds my eyepieces securely without any wiggle, and the fully multicoated optics deliver noticeably crisp, correctly oriented views of the moon even in my 80mm scope. It's a solid upgrade from my old star diagonal.

I was worried the tapered insert tube would make alignment tricky, but it slid right into my focuser perfectly. The fully multicoated optics actually make a noticeable difference in clarity on Jupiter’s bands. Exactly what I needed for comfortable daytime birding sessions.

The compression ring holds my eyepiece securely without any wobble, and the fully multicoated optics give nice bright views. I'm pleased with how crisp the image is, even at higher magnifications.
