Visual Adapter – CDK12.5

The step-down design from 2.75" to 2" is a perfect fit for my existing eyepieces, and the adapter itself slides in smoothly without any wobble. Setup took less than a minute.

Finally, a way to use my 2" eyepieces with this scope—the step‑down fits snugly and doesn't shift at all during focusing. The threading is smooth, and I noticed the inner bore is nicely blackened, which helps cut stray light.

I was worried the step-down might introduce some slop, but it fits snugly into the focuser and holds my diagonal perfectly steady. The 2" opening is exactly what I needed for my wider-field eyepieces.
