These Saxon ED Eyepieces able to provide high resolution and excellent sharpness while minimizing the chromatic aberration.
Why Choose Saxon ED Eyepieces?
ED Eyepieces are using two separate ED glass elements which able to provide better refractive properties if compared to standard optical glass, results in better colour correction. Visible colour differences between stars and planetary surface will give you more details while during observation.
ED Glass is often used in high-end Camera Lenses, Spotting Scopes and Refractor telescopes.
