Claire Y. ★★★★★

Finally got this adapter to mate my FIA100 focuser with the OPTEC-3600 rotator, and the thread alignment is perfect—no wobble at all. The brass threads feel much more durable than the plastic adapters I’ve tried before, and it holds my camera setup rock-solid.

Leo W. ★★★★★

Setup was a breeze—the threads caught perfectly on the first try and felt precise. My imaging train is now rock solid without any wobble.

Daniel J. ★★★★★

Finally, an adapter that actually threads on smoothly without that annoying wobble. Snug fit right out of the box, and my imaging train feels solid for the first time.
