The most versatile focal extender in the lineup — the Explore Scientific 1.25" 2x doubles the magnification of every eyepiece you own while preserving eye relief and field performance. Built around a telecentric 4-element optical design with EMD-enhanced multi-coatings on all air-to-glass surfaces, it delivers sharper edge performance and flatter fields than a traditional 2- or 3-element Barlow. The telecentric design also keeps magnification consistent regardless of spacing in the optical path — critical for imaging setups with filter wheels or flip mirrors.
A non-marring compression ring clamp holds eyepieces securely without scratching, and the double-tapered insert barrel ensures smooth, safe insertion into any 1.25" focuser. Threaded for standard 1.25" astronomy filters.
Key Features
- 4-element telecentric optical design — sharper fields and more consistent magnification than standard Barlows
- EMD-enhanced fully multi-coated optics with edge-blackened elements for maximum contrast
- Doubles your effective eyepiece collection without buying additional eyepieces
- Non-marring compression ring clamp and double-tapered insert barrel
- Threaded for 1.25" astronomy filters
Ideal For
- First-time extender buyers — the 2x factor is the most practical starting point, effectively turning three eyepieces into six focal lengths
- Planetary and lunar observing — push a comfortable 20mm eyepiece to 10mm-equivalent magnification with full eye relief
- Astrophotographers — telecentric design maintains consistent magnification through the imaging chain
