Reticle eyepieces Plössl with illuminated crosshairs 12.5mm 1.25"

The smaller the focal length of an eyepiece, the higher the magnification when used with a telescope.

The optical elements are treated with ultra-thin coatings. Among others, there are anti-reflective coatings for reducing, and dielectric coatings for increasing reflection.

Eyepieces are important accessories for every telescope.
