The Explore Scientific 2X 1.25" Focal Extender adds versatility to your eyepiece line-up, allowing you to double the magnification of any eyepiece of a compatible barrel size. You also keep the eye-relief of eyepiece, meaning more comfortable viewing, especially for eyeglass users.
Similar to a Barlow lens, this effectively doubles the focal length options of your eyepieces. However, compared to a Barlow lens, this four-element focal extender provides superior chromatic aberration control and field-flattening characteristics.
All air-to-lens surfaces are fully EMD-coated and each lens element is edge-blackened to produce superior contrast.
