Helical Adapter

By ROBERT A.

Very smooth travel for fine focusing.

The Orion 2"-1.25" Helical Fine-Focusing Adapter makes fine focusing a breeze. It replaces the 2" to 1.25" eyepiece adapter in scopes equipped with a 2" focuser, allowing very fine helical focusing with just a feather touch. Critical focus is easier to achieve and images stay steadier. It features dual rubber grip rings and setscrew lock. It works with 1.25" eyepieces. It requires at least 9mm inward focus travel.
