Julian ★★★★★

These extenders are machined precisely, so they thread on smoothly without any wobble. I stacked two to get the exact back focus I needed for my planetary camera.

John ★★★★★

Adding a quarter inch really dialed in my back focus for sharper stars. The stackable design means I can fine-tune the spacing without a ton of extra parts. A simple, effective fix for my imaging train.

Andrew ★★★★★

I was worried about getting the exact spacing right for my astrophotography rig, but this 1/4″ extender solved it perfectly. It threads on smoothly and the stackable design gives me tons of flexibility.
