This flat field eyepiece was designed to provide an ultra-sharp, ultra-clear, crisp image from the center all the way to the edge of the field of view.

FEATURES AND BENEFITS 65° field of view, crisp from center to edge Ultima Edge's wide, 65° apparent field of view allows you to see larger swaths of the night sky.

And while some eyepieces suffer from poor image quality at the edges, Ultima Edge's flat field design keeps the entire field sharp.

Excellent light transmission When more light travels through an eyepiece's optical path, the image you see is brighter and more detailed.

Ultima Edge features fully multi-coated optics and an 8-element lens design to maximize light transmission.
