David ★★★★★ Oct 21, 2026

Installed this on my 3.5" FeatherTouch and it fits perfectly—no wobble at all. The 37mm bore measurement is spot-on, making the SESTO SENSO solidly secure.

Sophia ★★★★★ Oct 20, 2026

Machined cleanly and the bore sits snug on the FeatherTouch shaft—zero wobble once you torque the set screws down. Took me five minutes to swap from the old adapter, and the focuser threads engage perfectly with the SENSO. Solid little upgrade.

Avery ★★★★★ Oct 18, 2026

Installing this adapter was straightforward and it locked onto my focuser shaft without any play. The machined fit is precise enough that I didn't need to fuss with shims, which saved me a good hour of setup time.
