Edward ★★★★★

Finally got the spacing I needed for back focus on my planetary camera setup. The threads are nicely machined and screw together smoothly without any wobble.

Violet C. ★★★★★

I needed a precise 20mm extension for my imaging train and this tube threaded on smoothly with no annoying wobble. The 6mm female depth held my filter securely without any tilt.

George M. ★★★★★

The female threads are nicely deep at about 6mm, so the tube screws on securely without any wobble. It gives me just the right spacing for my planetary imaging setup.
