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, 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 optical design with multiple precision lens elements.
For telescopes where a 2x or 3x doesn't reach your target magnification, the 5x closes the gap.
Key Features
- Four-element telecentric design, fully multi-coated with EMD coatings
- Filter thread for color and nebula filters
- 5x magnification
- Preserves the eye relief and comfort of your longer focal length eyepieces at extreme magnification
