Celestron Ultima Edge 30mm Flat Field Eyepiece - 2 inch

Built for wide, immersive views, the Celestron Ultima Edge 30mm Flat Field Eyepiece is a 2-inch telescope eyepiece with a 30mm focal length, a 70 apparent field of view and a 9-element optical design. Fully multi-coated optics and a flat-field layout keep the image sharp across the field, while the parfocal construction allows quick changes within the Ultima Edge range without refocusing, apart from the 24mm model.

The aluminium body has a black anodised finish and a moulded rubber grip ring for secure handling during observing sessions. A fold-down rubber eyeguard and 22mm eye relief support comfortable viewing with or without glasses. The 2-inch mounting barrel is internally threaded to accept standard 1. 25-inch filters and adaptors, and the eyepiece is compatible with 2-inch star diagonals and focusers.
