The Explore Scientific 5X 1.25" Focal Extender adds versatility to your eyepiece line-up, allowing you to quintuple the magnification of any eyepiece of a compatible barrel size.
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.
