Customer Reviews (4.8 / 5 · 5 reviews)

Elizabeth ★★★★★

Was looking for a solid upgrade for my 2" diagonal and this brass ring fits perfectly without any wobble. The threading is smooth and it holds my eyepieces securely.

George L. ★★★★★

Finally got tired of plastic compression rings cracking on my 2" diagonal, and this brass one fits snugly with zero play—the threads are smooth and the grip holds tight even when I'm switching eyepieces in the dark.

Henry ★★★★★

I’ve been swapping this brass ring between my 2” diagonal and barlow, and the threads engage smoothly every time—no wobble once it’s snugged down. It feels heavier and more precise than the plastic original, which is exactly what I wanted for keeping my eyepieces perfectly aligned.
