Overview
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 30mm Ultima Edge eyepiece features fully multi-coated optics and a 9-element, element lens design, maximizing light transmission.
The Ultima Edge 30mm has a generous 70° field of view perfect for viewing planets, stars and the Moon’s surface. This eyepiece provides low power magnification, perfect for deep sky objects and a bright detailed view of the moon’s surface.
Body
The 30mm Ultima Edge eyepiece’s main housing is machined from high grade aluminum with a black anodized outer surface.
Its 2" mounting barrel is internally threaded to accept standard 1.25" filters and adapters. It is compatible with 2” 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 30mm Ultima Edge eyepiece is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the rubber eyecups and long eye relief of 22mm.
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. 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: 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.
