¼
" eyepiece clamp with adapter B (typical for most
telescopes):
To use the eyepiece on a 1¼" eyepiece clamp, all you
have to do is unthread the 2" nosepiece.
The telescope adapter B is pre-mounted and fastened
onto the eyepiece by a knurled 2" locking ring.
The B-Adapter raises the eyepiece by almost 4mm, so
that the lower rim of the 2" locking ring is almost flush
with the 1 ¼" nosepiece. This configuration helps to use
the Mark IV with most 1¼" star diagonals, without having
the knurled ring touch the star diagonals eyepiece locking
screws (assuming the locking screws do not stick out
above the upper end of their star diagonal (see image on
the left).
Also all 1¼" filters will work in this configuration if thread-
ed onto the 1 ¼” nosepiece
2"-SC-thread
The Mark IV Zoom eyepiece also features a female 2" (SC) thread cut into the knurled
2” locking-ring. This universal standard thread can be utilized as soon as the 2" nose-
piece is being removed. In case the optical distance is critical or in case a theft proof
adaptation is preferred, this 2” thread fastens the Mark IV straight onto the backend
thread of SC-telescopes and their derivatives . Alter-natively the Mark IV directly adapts

onto the body of any Baader 2” star diagonal, with
the help of an optional 2"/2" inverter-ring (#1508020).
This ensures a permanent and very sturdy eyepiece
ad-aptation and saves about 45mm of optical length
(the closer distance even results in a slightly larger field
of view, in case you are using a Schmidt-Cassegrain
optics).
Connection options for spotting scopes
Spotting scopes with integrated 1¼" eyepiece
in most cases do not offer a lot of backfocus. Accordingly it is necessary to insert any
eyepiece as deeply as possible into the 1¼" clamp of the spotting scope to reach
infinity focus. Many eyepieces will fail at this operation since their field stop position is
not optimized for use at spotting scopes. On the Mark IV simply replace the telescope
adapter „B“ against the spotting scope
adapter „A“, as described on page 5, to
gain almost 4 mm in backfocus com-
pared to most other eyepieces. Then
re-attach the 1¼" nosepiece onto the
adapterring „A“, to use the Mark IV with
spotting scopes like the Zeiss Conquest
Gavia or the Celestron Regal M2, the
Hummingbird- or TrailSeeker-spotters
(image).

Connection options at the telescope-side
There are three principle ways to adapt the Hyperion Universal Zoom Mark IV onto a
telescope.
2" eyepiece barrel (intended for directly
adapting onto 2" stardiagonals):
The nosepieces for 2" and 1¼" are both
pre-mounted. The eyepiece fits "out-of-the-
box" onto all 2" eyepiece holders.
In this configuration, even all your 1¼"-filters
as well as 2"-filters can be mounted onto
either supplied barrel. But you can not use
1¼"- and 2"-filters at the same time.
For Zeiss-Diascope Spotting Scopes
use the optional
Zeiss-Diascope Bayonet Adapter 1¼" (#2454500). Configure
the eyepiece as described above with the Spotting Scope
Adapter A and the 1¼" nosepiece, then fasten the Bayonet
Adapter the Zeiss-Diascope at the 1¼" nosepiece.
