The Explore Scientific 2x Focal Extender (2") doubles your telescope's magnification for 2" eyepieces and imaging trains — ideal for bringing the Moon and planets in closer while keeping images sharp. 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

Observers and imagers working in the 2" format who want more magnification without swapping to shorter eyepieces. Want to understand power? See our guide to telescope magnification explained.

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.

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

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