Product description

This product combines the excellent image quality and viewing comfort of our TSWA Erfle wide angle eyepieces with a reticle for guiding. The reticle can be illuminated with the optional illuminator.

The laser engraved reticle has very fine lines which are seen in fine contrast to the sky's background, as long as the sky has slight background illumination. With the optional illuminator the crosshair can be seen even under perfectly dark skies. It will then glow in faint red.
