Daniel F. ★★★★★

The internal threading is nicely machined and the 30mm length perfectly bridges the gap for my optical train. Screws on smooth and solid, no wobble or light leaks.

Eli O. ★★★★★

Was worried the 30mm length wouldn't be enough, but this extension tube gave me just the right spacing for my camera sensor. The threads are nicely machined and screw on smoothly without any wobble. Works perfectly for achieving proper focus with my setup.

Isabella ★★★★★

I needed a bit more back focus for my planetary camera, and this tube's 30mm length was exactly what I was missing. The threads on both ends fit snugly with no play, and the 2-inch diameter matched my focuser perfectly.
