Celestron Ultima Edge 10mm Flat Field Eyepiece - 1.25 inch

For observers who want a flatter, more evenly corrected view across the field, the Celestron Ultima Edge 10mm Flat Field Eyepiece brings a compact 1. 25-inch format together with a 5-element optical design and a 60 apparent field of view. This telescope eyepiece is built for 1. 25-inch focusers and is compatible with 1. 25-inch star diagonals, filters and adapters via its internally threaded barrel.

Fully multi-coated optics support light transmission, while the 10mm focal length provides high-power viewing for closer study of smaller celestial targets. A 16mm eye relief, fold-down rubber eyeguard and moulded rubber grip ring make handling and viewing more comfortable, including for eyeglass wearers. The aluminium body has a black anodised finish, and the parfocal design allows quick changes within the Ultima Edge line without refocusing, with the stated exception of the Ultima Edge 24mm.
