Customer Reviews (4.6 / 5 · 5 reviews)

Charlotte S. ★★★★★

Was getting a bit of vignetting with my binoviewer setup, and this adapter solved it by letting the eyepiece sit deeper into the focuser. The machined threads are smooth and it locks tight without any play.

Brian Q. ★★★★★

I was struggling with eyepiece height on my dob, but this adapter shaves off that extra half-inch and really helps with stability at high magnifications. Works perfectly with my existing 2" focuser.

Ava ★★★★★

Finally, a way to get my 1.25" eyepieces sitting 0.5" lower without swapping out the whole focuser. Fits snugly in any 2" drawtube and the inset design keeps the eye position comfortable even on short refractors. My astigmatism has never been happier.
