Explore Scientific 3x 1.25" Focal Extender lens

The 1.25" barrel diameter 3x Focal Extender from Explore Scientific triples the magnification of any 1.25" eyepiece, adding another layer of usability to the eyepieces you have. Additionally, since low-power eyepieces often offer a longer eye relief than high-magnification ones, using this focal extender gives you the benefit of comfortable viewing, while increasing the magnification. This extender features a fully multicoated 4-element optical configuration to produce bright images with true color representation without distortion across the entire field of view.
