Scarlett ★★★★★ Oct 20, 2026

I needed a bit more reach for my 1.25" eyepieces, and this extension does the job perfectly — the brass locking ring holds everything securely with no wobble. It's solid and exactly as described.

Harper W. ★★★★★ Oct 19, 2026

The brass locking ring on this extension grips tight with no wobble, which was my main worry. Adds just the right spacing for my 2" eyepieces to reach focus without any hassle.

Evelyn ★★★★★ Oct 18, 2026

I needed a bit more room between my scope and camera, and this extension does exactly that. The brass locking ring feels solid and holds my 1.25" adapter without any slipping during focusing.
