The Explore Scientific 2x Focal Extender (1.25") doubles your telescope's magnification, turning any 1.25" eyepiece into a higher-power one for closer views of the Moon and planets. Its multi-element telecentric design keeps the light path parallel, so magnification stays consistent and images stay sharp with comfortable eye relief — a step up from a simple Barlow lens.

Who it's for

Lunar and planetary observers (and imagers) who want more magnification from the eyepieces they already own. Want to understand power? See our guide to telescope magnification explained.

Frequently asked questions

How is a focal extender different from a Barlow?
A focal extender uses a telecentric design that keeps light rays parallel, giving more consistent magnification and better performance with filters, binoviewers, and cameras than a simple Barlow.

How much magnification will I get?
It doubles whatever your eyepiece already gives. For example, a 10mm eyepiece behaves like a 5mm, doubling the power.

Can I use it for astrophotography?
Yes — it's well suited to planetary and lunar imaging where extra image scale helps.
