Customer Reviews (4.4 / 5 · 5 reviews)

Nicholas ★★★★★

This ring made my NexStar 4 ready for a 2-inch diagonal without any wobble or fuss. The threads are precise and smooth, so attaching it took less than a minute. Perfect for anyone wanting a solid SCT connection.

Eli ★★★★★

This ring let me attach my 2-inch diagonal to my C90 without any wobble or adapter stacking. The brass compression ring holds eyepieces securely and the anodized finish looks great.

Carter U. ★★★★★

The machining is precise and the threads mate perfectly with my SCT setup. It's a solid brass piece that feels much more substantial than the plastic adapters I've used before.
