Customer Reviews (4.8 / 5 · 5 reviews)

Steven M. ★★★★★

I was worried the threads might be shallow, but they gripped firmly on both sides—no wobble at all. The 10mm length was exactly what I needed to reach focus with my new filter wheel.

Carter ★★★★★

Finally got my backfocus dialed in for the refractor—this 10mm spacer did the trick. The female thread is deep enough that everything seated snug without any tilt. Solid little piece for the price.

Matthew ★★★★★

The threading on this extension tube is surprisingly precise—it screws on smoothly without any wobble. The 10mm length was exactly what I needed to reach focus with my camera and telescope combo.
