Explore Scientific 2" 3X Focal Extender

The Explore Scientific 2" 3x Focal Extender triples the magnification of your 2" and 1.25" eyepieces, pushing wide-field eyepieces into high-power territory while keeping their eye relief. A 30mm 2" eyepiece becomes a 10mm equivalent with the same comfortable viewing position, ideal for planetary detail work with premium glass.

The telecentric optical design, with multiple precision lens elements, has EMD-enhanced multi-coatings on all air-to-glass surfaces. Edge-blackened elements suppress stray light for clean contrast on bright targets like Jupiter and the Moon. Magnification stays consistent regardless of spacing in the optical path, which is important for imaging rigs with accessories between the extender and camera.

It is the higher-power of Explore Scientific's two 2" focal extenders (2X and 3X). A 1.25" eyepiece adapter is included for full compatibility with both barrel sizes.
