Celestron Ultima Edge Eyepiece - 1.25" 10mm

The Celestron Ultima Edge 10mm Eyepiece is designed to deliver ultra-sharp, clear images from the center to the edge of the field of view. Its five-element optical design features fully multi-coated optics to maximize light transmission and image clarity. With a generous 60° apparent field of view, it is ideal for observing planets, stars, and lunar surface details. Its high magnification makes it especially suitable for viewing smaller celestial objects up close.

Durable Design and Comfortable Viewing

The eyepiece features a high-grade aluminum housing with a black-anodized finish for durability. Its 1.25-inch threaded barrel accepts compatible filters and adapters and fits standard 1.25-inch star diagonals and focusers. A specially designed molded rubber grip provides secure, slip-resistant handling, even when wearing gloves.
With 16mm of eye relief and a fold-down rubber eyecup, the Ultima Edge 10mm offers comfortable viewing for users with or without eyeglasses.

Convenient Parfocal Design

Ultima Edge eyepieces feature a parfocal design, allowing you to switch between compatible eyepieces in the series with minimal or no refocusing. This makes it easy to move between different magnifications and spend more time observing.

Note: The Ultima Edge 24mm is not parfocal. The parfocal design applies only within the Ultima Edge series and does not guarantee focus compatibility with eyepieces from other brands or series.
