The Explore Scientific 1.25" 2x Focal Extender (FE02-125) enhances your telescope’s performance by doubling the magnification of any compatible 1.25" eyepiece. This high-precision optical accessory effectively expands your available magnification options without the need to purchase additional high-power eyepieces. Because focal extenders preserve the long eye relief of lower-power eyepieces, users benefit from improved viewing comfort, especially when observing at high magnification.

Built with a four-element, fully multi-coated optical design, the FE02-125 delivers bright, high-contrast images with excellent color accuracy. Edge-blackened lenses minimize internal reflections, while the compact 1.25" format ensures compatibility with most standard focusers, diagonals, and eyepiece holders. This focal extender is an ideal upgrade for planetary, lunar, and detailed deep-sky viewing—providing more versatility and value from the eyepieces you already own.
