Explore Scientific 1.25" 3X Focal Extender

The Explore Scientific 1.25-inch 3X Focal Extender doubles the number of magnifications available from an eyepiece collection, letting three eyepieces effectively cover six magnification choices without buying more glass. Because lower-power eyepieces usually have more generous eye relief than high-power ones, using the extender to boost magnification keeps that comfortable eye relief — a real benefit for eyeglass wearers or owners of fast telescopes pushing high-power eyepieces. It's part of a 2x/3x/5x extender lineup, so it can be matched to whatever magnification jump a telescope setup needs.

• 3x magnification boost: Effectively doubles an eyepiece collection's magnification options — three eyepieces become six choices with the extender added.
• Preserves eye relief: Lets a shooter reach higher effective magnification while keeping the more generous eye relief of a lower-power eyepiece, useful for eyeglass wearers.
• 1.25" barrel size: Fits standard 1.25-inch barrel eyepieces and accessories.
• Compact design: Measures 93mm long and 45mm wide, weighing 249 grams (8.7oz).
• Part of a matched lineup: Available in 2x, 3x, and 5x models to suit different telescope and eyepiece combinations.
