High-power, ultra-sharp wide-field eyepiece for planets, Moon & detailed deep-sky observing
The Ultima Edge 10mm Flat Field Eyepiece is a premium 1.25″ parfocal Ultra Flat Field (UFF) eyepiece engineered to deliver exceptionally crisp, contrast-rich views from the center all the way to the edge of the field. Designed for serious visual astronomers, this eyepiece combines a proprietary 5-element optical design, fully multi-coated optics, and a comfortable viewing experience—perfect for high-magnification planetary, lunar, and small deep-sky targets.
“See the whole picture” with Ultima Edge. This eyepiece is purpose-built to provide pinpoint stars and uniform focus across the entire 60° apparent field of view, minimizing field curvature and astigmatism common in standard eyepieces—especially noticeable at higher magnifications.
10mm focal length delivers high-power magnification for fine lunar detail, planetary features, double stars, and compact deep-sky objects
Wide 60° AFOV creates an immersive view while keeping targets comfortably in frame
Fully multi-coated optics maximize light transmission and contrast
5 lens elements in 4 groups with proprietary optical design
Generous 16mm eye relief—excellent for eyeglass wearers
Fold-down rubber eyeguard for flexible eye positioning
Parfocal design lets you switch between Ultima Edge eyepieces with minimal refocusing
Note: The Ultima Edge 24mm is not parfocal. Parfocality applies within the Ultima Edge line only.
Crafted for durability and ease of use, the eyepiece body is machined from high-grade aluminum with a black anodized finish. A molded rubber grip ring ensures secure, non-slip handling—even with gloves during cold nights.
