What are ED eyepieces and how are they different?

ED eyepieces use two separate ED glass elements that provides superior refractive properties compared to standard optical glass. This results in better colour correction, with truer colour differences visible between stars and planetary surface details.

ED glass is often used in high-end camera lenses and refractor telescopes.
