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.
