The Celestron Ultima Edge 15mm 1.25" eyepiece features a flat-field 8-element lens design which provides ultra-sharp, crisp images all the way to the edge of the field of view.
The Ultima Edge 15mm has a generous 65° apparent field of view, perfect for viewing planets, stars and the Moon’s surface. This eyepiece provides medium power magnification, perfect for those times when you want to get up close to smaller objects.
The 15mm Ultima Edge eyepiece’s main housing is machined from high grade aluminium with a black anodized outer surface. Its 1.25" mounting barrel is internally threaded to accept standard 1.25" filters and adapters. It is compatible with 1.25” star diagonals and focusers.
On the exterior of the eyepiece, you will find a uniquely designed, moulded rubber grip ring for non-slip handling during observing sessions, even if you have gloves on.
Viewing through the 15mm Ultima Edge eyepiece is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the fold-down rubber eyecups and long eye relief of 16mm.
When you buy more than one Ultima Edge eyepiece, you can switch between them without refocusing thanks to their parfocal design. With a set of Ultima Edge eyepieces in your kit, you'll be able to enjoy a wide range of high and low power views - and switch between them quickly and easily. That means you can get more out of every observing session.
Note: the Ultima Edge 24mm is not a parfocal eyepiece. Ultima Edge eyepieces are only parfocal within the line and do not maintain focus when swapped with parfocal eyepieces from other brands or series.
