Included Eyecups
Three different eyecups are in-
cluded with the Mark IV Zoom.
Choose the eyecup according
to your preferences or de-
sired eye relief (with or without
glasses):
1. Initially mounted is the large
height-adjustable eyecup that
also fastens onto the M43
photo-thread of the eyepiece. By
rotating it counterclockwise the height will increase. This eyecup
easily unthreads by simply rotating it upwards further than the
uppermost stop - this reveals the M43-thread connection.
2. A none-folding rubber eyecup alternatively fits straight onto the M43-
thread. This is the preferred solution for observers without glasses at a
binoviewer. It gives you enough room for your nose and good support
to keep the perfect eye distance.
3. An even lower eyecup with foldable winged eye shield especially
serves for wearers of eye glasses, the flappable side shields block
stray light and side image information not part of the eyepiece field of
view. This helps to concentrate on the target when using a binoviewer.
In case of need an optional, 7.5mm height extension tube with M43-
threads (#2954250) is available for further finetuning the position of the
eyecups. This extension tube has one male and one female M43-thread.

Three eyecups are shipped together with the
eyepiece. The M43-adapterthread is located
on the top of the eyepiece.
The height of the large
eyecup can be adjusted.

Spotting Scope
Adapter A
Changing the mounting adapters A and B
In the standard configuration, both 1¼" and 2" nosepieces are mounted at the eye-
piece main body, including dustcaps. Remove both dust caps before using the eye-
piece for the first time. This way you can use it at telescopes with 2" eyepiece clamp.
For telescopes or spotters with 1¼" clamp, it is necessary to reconfigure the eyepiece
as shown below. Reconfiguring the eyepiece is always done according to the following
scheme:
1.
Removing the 2" nosepiece
:
Hold the eyepiece at the locking ring
, which also has
a 2" female thread inside, and unthread the nosepiece
counterclockwise. Now you can access the 1¼" nose-
piece, the female 2" SC-thread and the adapterring B
(for telescopes). This way, you can use the eyepiece
e.g. at telescopes with 1¼" eyepiece holder or at tele-
scopes, prisms and mirrors with male 2"-SC-thread.
2.
Removing the 1¼" nosepiece
:
Remove the nosepiece by rotating it counterclock-
wise. Now you can see the 1

" thread of the tele-
scope-adapter B
(or of the spotting-scope-adapter
A), and you can screw the eyepiece directly onto many
smaller spotting scopes (e.g. Celestron Ultima, Sky-
watcher).
3.
Replacing the adapterring for telescopes (B)
or spotting scopes (A)
:
Completely unscrew the knurled 2" locking ring
from the bottom end of the eyepiece and replace the
pre-mounted ring "B" (for instance) against the other
supplied ring "A" or vice versa. Always orient the rings
in a way that you can see the engravement. Now thread
the knurled locking ring back onto the eyepiece to fix
the adapterring in its place. Do not use force.
The 1¼" nosepiece fits onto both of the adapter-rings („A“ and „B“).
Continously adjustable Magnifications
with ClickStops at 8/12/16/20/24mm
The Hyperion Universal Zoom Eyepiece can be ad-
justed steplessly from 8 to 24 mm of focal length. In
addition the focal lengths 8 / 12 / 16 / 20 / 24 mm are
marked with „ClickStops“, 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 ob-
servation without eye-strain – even in the dark. The click-sound has been smoothened,
so that hunters or birders will not disturb their targets when zooming in on them.
