Product description
TS WA 20mm 1,25" Wide angle Erfle with crosshair

Combine a brilliant wide-angle ERFLE eyepiece with a fine reticle, that can even be illuminated. The crosshair is laser-engraved and very subtle. The reticle won't bother you during observation. It only gently stands out from the background. The optional illumination makes it even more convenient, due to its subtle red glow.

Applications

Build yourself a finderscope using the Erfle or use it for astrophotography. You can also combine the eyepiece with a Barlow lens, to achieve higher magnification. Observing through the eyepiece is a lot more convenient, than compared with other reticle eyepieces.
