The Ascension ED eyepieces are ideal for observing all types of astronomical objects, from the moon and the planets to nebulas and galaxies. Special ED glass is used in two out of the six elements minimizing chromatic aberrations.

The latest generation of the Ascension ED eyepieces use broadband fully multicoated optics that provide excellent image brightness and contrast while internal reflection effects are kept to a minimum. All eyepieces in the range are par focal. Long eye relief makes these eyepieces a pleasure to use and are highly recommended for people that wear spectacles.

These Ascension eyepieces offer superior performance due to the inclusion of two ED optical elements rather than just the one, typically offered in other ED designs.
