Adapter, CDK17/20 to Clement Focuser

Machined perfectly to match the OEM retaining ring, this adapter let me swap my focuser without any wobble or tilt. Solid aluminum construction gives a reassuringly firm connection to the back of the OTA.

Finally, a clean way to attach my focuser without the stock setup. The retaining ring design matched perfectly, so it felt rock solid right out of the box. No wobble at all during my first clear night.

This adapter let me ditch the Hedrick focuser and mount my Clement directly — the retaining ring alignment was spot on. Focus is noticeably more solid now with less flex.
