The fourth generation of Hyperion
®
Zoom eyepiece
Since its introduction to the market, the Hyperion
®
Zoom has been improved again
and again. The current generation of this eyepiece weighs 290 gram and is lighter by
80 grams than its predecessor – it now also has a diameter of only 55 mm, perfect for
binoviewers. The zooming-mechanism as well as the inner zooming rails for all lens
groups have been modified to improve operation at cold temperatures and the parfo-
calty for each focal length has been finetuned.
Most important however – the Mark IV offers almost 4 mm more backfocus. This is
most beneficial for application with a multitude of spotting scopes. By utilizing the
supplied spotting-scope adapter ring "A", the Hyperion
®
Universal Zoom almost
reaches four mm deeper into the eyepiece clamp of spotting scopes designes for 1¼"
eyepieces, to safely reach infinity focus.
The Mark IV comes with both the 2" and 1¼" nosepieces mounted, both are free of
the hated undercuts. Instead, our proprietary Zero-Tilt Safety-Kerfs provide an added
measure of security by reducing the tendency of an eyepiece to slip from an unlocked
eyepiece clamp. An additional little feature is the Baader-yellow soft pouch with inte-
grated belt strap – which fastens onto many tripod legs just as well, to serve as a bin
for all dustcaps that may go astray otherwise.
Unchanged are the optical quality, 68° field of view at highest magnification, Phantom
Group multicoatings, a large adjustable eyecup or alternatively two M43 rubber eye-
cups for bino viewing. The Mark IV likewise accepts adaptation of the 2.25x Hyperion
®
Barlow onto the 1¼" nosepiece, featuring the magnification range of 3.6 to 10.7 mm.
Continously adjustable Magnification
with ClickStops at 8 / 12 / 16 / 20 / 24 mm
The Hyperion
®
Universal Zoom Eyepiece can be adjusted steplessly from 8 to 24 mm of
focal length. In addition the focal lengths 8 / 12 / 16 / 20 / 24 mm are marked with „Click-
Stops“, so that any of these five magnifications can
be set intuitively. This is especially of importance
for use with binoviewers, to easily and precisely set
two Mark IV eyepieces to the same focal length for
effortless binocular observation without eye-strain –
even in the dark. The click-sound has been smooth-
ened, so that hunters or birders will not disturb their
targets when zooming in on them.
