The Explore Scientific 3x Focal Extender (2") triples your telescope's magnification for 2" eyepieces and imaging trains — bringing the Moon and planets in close for high-power views and photography. Its telecentric multi-element design keeps the light path parallel for consistent magnification and clean, flat fields, outperforming a simple Barlow lens.

Who it's for

Frequently asked questions

Why choose the 2" version?
The 2" focal extender suits 2" eyepieces and larger imaging trains without vignetting. Choose a 1.25" extender for 1.25" eyepieces and smaller cameras.

Will 3× be too much power?
3× is best on steady nights and with telescopes that support high magnification; on turbulent nights a 2× may give a cleaner view.

How is it different from a Barlow?
Its telecentric design keeps light rays parallel for consistent magnification and better performance with cameras and filters.
