BAADER Hyperion Zoom Mark IV, 8-24mm eyepiece (1¼" / 2")

Zoom-lenses in general are not really famous for high quality optics. Also many zoom-eyepieces do not deliver the best possible image quality at high magnification because they were designed with focus on the price-tag so that image sharpness and field size is getting worse with increased magnification.

The recognition that the Hyperion Zoom Eyepiece enjoys is based on the fact that it was designed the other way around: the glass selection and most of all the principal optical design and consequently the lens polish quality – all were optimized for the highest magnification. And obviously, when closing in on an object you will want the field of view to increase and not to have it become seemingly smaller. Hence the Hyperion-Zoom shows the largest apparent field of view at highest magnification.

For many birders, observers of nature and astronomers alike, the Hyperion Zoom Eyepiece is their favorite eyepiece, it is also the only zoom-eyepiece that was designed from ground up to be used with bino-viewers.
