The Explore Scientific 1.25" 5x Focal Extender is purpose-built for extreme planetary magnification. It turns a comfortable 20mm eyepiece into a 4mm equivalent — delivering the power to resolve fine detail on Jupiter, Saturn's Cassini Division, and lunar rilles, all while keeping the generous eye relief of your longer focal length eyepiece.

Like every model in the Explore Scientific focal extender line, the 5x uses a telecentric 4-element optical design with EMD-enhanced multi-coatings on all air-to-glass surfaces and edge-blackened elements for maximum contrast. The 4-element design delivers significantly sharper edge performance and flatter fields than a standard Barlow at equivalent magnification. Threaded for standard 1.25" astronomy filters.

Explore Scientific describes the 5x as "a perfect match for short focal length refractors or reflectors — particularly for viewing or imaging planets in minute detail." For telescopes where a 2x or 3x doesn't reach your target magnification, the 5x closes the gap.


Key Features
  • 4-element telecentric optical design with EMD-enhanced fully multi-coated optics
  • 5x magnification — the highest multiplier available in a 1.25" focal extender
  • Preserves the eye relief and comfort of your longer focal length eyepieces at extreme magnification
  • Non-marring compression ring clamp and double-tapered insert barrel
  • Threaded for 1.25" astronomy filters

Ideal For
  • Dedicated planetary observers — reach extreme magnification without sacrificing eye relief
  • Short focal length telescopes — ideal for fast refractors and reflectors that need a bigger magnification boost to reach planetary detail
  • High-resolution lunar imaging — push camera-equipped setups to maximum image scale

Impressive Chair for the price!
Color: Black
Purchased for my mother, she absolutely loves it. She used a secretary style chair forever and said she didn't want a big bulky chair like the executive type until she saw this one. It's comfortable like an executive chair but not quite a big or cumbersome as the executive can be. It took a hot minute to put together but well worth it. Instructions were very clear and easy, I'm in my 60's, if I can put it together anybody can! Chair is well made, solid!
