Penelope ★★★★★ Oct 21, 2026

The compression ring holds my 1.25" eyepieces perfectly centered without any wobble—much better than the set-screw type I used before. The anodized finish feels solid and threads smoothly onto my 2" filter.

Matthew M. ★★★★★ Oct 19, 2026

The compression ring grips my eyepieces securely without any wobble, and the anodized finish feels solid. Threaded for 2" filters, it's a clean upgrade from my old set-screw adapter.

Charlotte ★★★★★ Oct 18, 2026

Swapped out a cheap set-screw adapter for this one and the difference is night and day—the compression ring holds my eyepiece dead center without any wobble. The anodized finish feels solid and threads smoothly onto my 2" filter. Exactly what I needed for a secure fit.
