Better Focusing Precision for High-Power Viewing. Focusing at high magnification with a standard rack-and-pinion focuser can be a real challenge. The focuser action is coarse, making it hard to nail the exact focus point. This precision-machined 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. Features dual rubber grip rings and setscrew lock. Works with 1.25" eyepieces. Requires at least 9mm inward focus travel. NOTE: Orion's Shipping Price for this item by itself is $6.95
