Body

The 30mm Ultima Edge eyepiece’s main housing is machined from high grade aluminium with a black anodized outer surface. Its 2"/50.8mm mounting barrel is internally threaded to accept standard 2"/50.8mm filters and adapters. It is compatible with 2”/50.8mm 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.

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.
