Universal Zoom MARK IV
– WITH 1¼" AND 2" NOSEPIECE –
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 are getting worse
with increased magnification.
The good reputation 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 mag-
nification. 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 high-
est 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 de-
signed from ground up to be used with bino-viewers.
