Customer Reviews (4.8 / 5 · 5 reviews)

Ava F. ★★★★★

The bull-nosed design makes it easy to grip while swapping out eyepieces, and the threads are buttery smooth. It locked onto my field flattener without any play.

Benjamin ★★★★★

Was a bit worried about the fit on my 2" focuser, but the bull-nosed taper seats snugly with zero play. Threads on the flattener side are clean and catch easily, so the whole setup feels solid under the camera.

Violet Z. ★★★★★

The bull-nosed profile fit perfectly into my focuser without any play, and it let me finally use that 0.7x reducer with my 2" setup to get wider field shots.
