Hannah ★★★★★ Oct 21, 2026

Installed this on my FC-100 and the stars are finally sharp corner-to-corner. The threading was precise and it mounted without any wobble.

Ryan Z. ★★★★★ Oct 20, 2026

Finally got my FC-100D dialed in with this ring—the threading is precise and it seated perfectly flush. The stars are sharp corner to corner now, exactly what I was hoping for.

Penelope ★★★★★ Oct 19, 2026

Screwed this onto my FC-100D last night and the stars across the entire frame are perfectly round now—no more coma at the edges. The threads are smooth and the fit is precise, no wobble at all.
