See the whole picture with Ultima Edge. These flat-field eyepieces were designed to provide an ultra-sharp, ultra-clear, crisp image from the center all the way to the edge of the field of view. The 18mm Ultima Edge eyepiece features fully multi-coated optics and an 8- element lens design, maximizing light transmission.

The Ultima Edge 18mm has a generous 65° field of view perfect for viewing planets, stars and the Moon's surface. This eyepiece provides higher-powered magnification, perfect for those times when you want to get up close to smaller objects.

Body

The 18mm Ultima Edge eyepiece's main housing is machined from high grade aluminum 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, molded rubber grip ring for non-slip handling during observing sessions.

Viewing through the 18mm Ultima Edge eyepiece is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the rubber eyecups and long eye relief of 20mm.

Convenient Parfocal Design

Spend more time observing and less time focusing! When you buy more than one Ultima Edge eyepiece, you can switch between them without refocusing thanks to their parfocal design.

That means you can get more out of every observing session.
