Ella ★★★★★

Machined perfectly—threaded right onto my CDK20 without any wobble or need for shims. The anodized finish matches the rest of the setup nicely too.

Violet W. ★★★★★

That bolt pattern on the back of the 3.5 inch focuser lined up perfectly with my CDK17’s existing rear cell, no shimming needed. Threading on my AP camera was smooth and snug, so I can finally trust the connection during long exposures.

Sophia ★★★★★

Finally getting a solid connection between my Hedrick focuser and the AP threads—no more wobble or guesswork. The aluminum feels well-machined, and it seated perfectly without any filing or shimming.
