The Hyperion
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 mag-
nication because they were designed with focus on
the price-tag so that image sharpness and eld size is
getting worse with increased magnication.
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 high-
est magnication. And obviously, when closing in on
an object you will want the eld of view to increase
and not to have it become seemingly smaller. Hence
the Hyperion-Zoom shows the largest apparent eld of view at highest magnication.
For many birders, observers of nature and astronomers alike, the Hyperion Zoom Eye-
piece is their favorite eyepiece, it is also the only zoom-eyepiece that was designed
from ground up to be used with bino-viewers.

What's new on the Universal Zoom Mark IV?
The fourth generation of this eyepiece weighs 290 gram and is lighter by 80 grams
than its predecessor – it now has 55 mm diameter to become useful in dual mode
from 55 mm interpupillary distance, both features make it especially desirable for use
with bino-viewers. The adjustable eyecup can be removed to expose the M43 video/
photo thread and create the maximum "nose space" for using it on binocular viewers
with the supplied winged rubber eyecups - for maximum concentration on the target.
The click-stop action has been smoothed out to more easily access the magnication
stops at 8/12/16/20 and 24mm. The zooming-mechanism as well as the inner zoom-
ing rails for all lens groups have been modied to improve cold temperature operation
and the parfocalty for each focal length has been netuned.
Most important however – the Mark IV offers almost 4 mm more backfocus. This is
most benecial for application with a multitude of spotting scopes. Many spotting
scopes nowadays do allow the mechanical insertion of astronomical 1¼" eyepiec-
es – but in many cases this combo cannot focus to innity. By utilizing the supplied
spotting-scope adapter ring "A", the Hyperion Universal Zoom almost reaches four
mm deeper into the eyepiece clamp of all those spotters, to safely reach innity focus.
When using the Mark IV on a telescope though, the "B"-ring (supplied) should be cho-
sen instead, to keep the bottom of the eyepiece ush with the upper end of most star
diagonals. Otherwise the bottom 2" SC-threaded holding ring that holds the "A" or "B"
ring in place may directly rest on the clamping screws of the star diagonal.
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 is the optical quality, 68° eld of view at highest magnication, Phan-
tom Group multicoatings, a large adjustable eyecup or alternatively two M43 rubber
eyecups for bino viewing. An optional spacer ring M43/M43 (#2954250) with 7,5 mm
extension enables the user to increase the height of these eyecups in case of need.
The Mark IV likewise accepts adaptation of the 2.25x Hyperion-Barlow onto the 1¼" nose-
piece, to transform into a high power zoom, featuring the magnication range of 3.6 to
10.7 mm. The Hyperion Universal Zoom Mark IV is available individually (#2454826) or as
set together with the 2.25x Hyperion Barlow (#2454827)

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 ts 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 appable side shields block
stray light and side image information not part of the eyepiece eld 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 netuning 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.

Spotting Scope
Adapter A
Changing the mounting adapters A and B
In the standard conguration, 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 rst time. This way you can use it at telescopes with 2" eyepiece clamp.
For telescopes or spotters with 1¼" clamp, it is necessary to recongure the eyepiece
as shown below. Reconguring 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 13 /
8" 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 x
the adapterring in its place. Do not use force.
The 1¼" nosepiece ts 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 ve
magnications 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.

1¼" 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 ush
with the 1 ¼" nosepiece. This conguration 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" lters will work in this conguration 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
Spotting Scopes with 13 /
8" male thread
(e.g. many Skywatcher, Orion, Acuter, Synta and Celestron spotting
scopes) can be used directly with the Hyperion Zoom Mark IV.
Just unthread the 1¼" nosepiece to
expose the 13 /
8" female thread inside the
adapterring „A“ and thread the eyepiece
onto the spotting scope.
This way a very short adaptation onto the
spotting scope is achieved – ensuring to reach
innity focus. Adapters to spotting scopes of
other manufacturers are under preparation.
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 eld
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
innity focus. Many eyepieces will fail at this operation since their eld 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).
Zeiss Diascope Adapter
# 2454500
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 ts "out-of-the-
box" onto all 2" eyepiece holders.
In this conguration, even all your 1¼"-lters
as well as 2"-lters can be mounted onto
either supplied barrel. But you can not use
1¼"- and 2"-lters at the same time.
For Zeiss-Diascope Spotting Scopes use the optional
Zeiss-Diascope Bayonet Adapter 1¼" (#2454500). Congure
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.

Attaching cameras with mounted lenses by their front-lens filter threads
Most camera lenses attach onto the Mark IV (or any Hyperion or Morpheus eyepiece)
by using the Baader SP54-system-thread, together with a whole family of Hyperion
DT-Rings. For this system, the adapter M43/SP54 #2958086 is available, which ts
directly onto the Mark IV. This SP54 adapter is the base to adapt the Mark IV onto all
common camera lenses with a lter thread and allows to use any such lens and cam-
era for afocal projection imaging.
The SP 54 step-rings for making this system most versatile are called „Hyperion
DT-Rings“. Choose the appropriate adapter from SP54 onto the lter thread of your
lens by reading the tread size at the engravement around the front lens of your cam-
era-lens . Following SP54 step-rings are available:
SP54 to M28: #2958028
(requires also 2958090)
SP54 to M37: #2958037
(requires also 2958090)
SP54 to M46: #2958046
SP54 to M49: #2958049
SP54 to M52: #2958052
SP54 to M55: #2958055
SP54 to M58: #2958058
SP54 to M62: #2958062
For more information, please visit: www.baader-planetarium.com/en/eyepiece-accessories
These step-rings are designed to ensure the shortest possible distance be-
tween eyepiece and camera front lens. This is crucial to reduce or complete-
ly avoid vignetting. The M62-ring can even serve as base for further Hyperi-
on-stepper-rings to adapt lenses with up to 82 mm front lter threads – but the
spacing increases and the eyepiece – camera distance becomes less optimal.
For cameras with M43-thread, we recommend to use the M43 Extension Ring
#2954250 to gain some safety distance, in case there is a risk that the lenses
of the camera and eyepiece may touch (see image to the right). Check for
correct spacing of the connection before threading camera lens and Mark IV
completely to avoid damage to your valuable camera lenses.

The Zeiss Diascope 85 T/FL in combination with
the Hyperion Universal Zoom Mark IV (right) offers
ve different steadily increasing magnications
instead of one magnication:
Connection options for cameras and video photography
Attaching a camery body (DSLR and System-Cameras)
After removing the height-adjustable eyecup, the universal M43-thread is exposed. This
type of thread is used by most video-cameras. Baader Planetarium offers many step-up-
or step-down-rings for most common threads of camera lenses, as well as the adapter
#2958080 to convert from M43 to the universal photographic T-2-thread (M42x0,75).
All standard-T-rings for DSLR-cameras do attach onto this (#2958080) T-2 thread. In this
way, a camera body attaches onto the Mark IV (without camera-lens). Now the Mark IV
Zoom becomes a digiscoping projection optics, also featuring variable magnication.
A full-frame-DSLR will require an added ~40 mm of distance between the camera T-2-
ring and the Mark IV T-2 ringed eyepiece. This is advisable to retain the at eld of the
Mark IV. For smaller APS-C-cameras, only ~30 mm of distance are recommended. We
propose the use of an optional quick-changer, for instance the TQC/TCR Heavy Duty
T-2 Quick Changing System (#2456322). In this way the camera orientation can be ad-
justed easily, to align the camera with the optical axis or to remove the camera body for
a quick look into the eyepiece. We recommend the following combinations:
For Full Frame Cameras:
• M43/T-2 Adapter (#2958080), TQC/TCR Quick Changing System (#2456322),
T-2 extension tube 15mm (#1508154), T-2 extension tube 7,5mm (#1508155)
~ 40mm optical length
• Alternatively: M43/T-2 Adapter (#2958080), extension tube 40mm (#1508153)
~ 41,5mm optical length
For APS-C:
• M43/T-2 Adapter (#2958080), TQC/TCR Quick Changing System (#2456322),
T-2 extension tube 15mm (#1508154)
~ 32,5mm optical length
• Alternatively: M43/T-2 Adapter (#2958080), 2x T-2 extension tube 15mm (#1508154)
~ 31,5mm optical length
The magnication will increase when inserting additional T-2 extension tubes, but this
will also greatly increase the exposure time.
The setups above enable the Mark IV to work very similar to a dedicated photo-adapt-
er as offered by many manufacturers of spotting scopes (e.g. the Zeiss-Photoadapter
(#528030, offering but one xed magnication). However - the Mark IV will provide a
wide range of magnication.
Example: The Zeiss Diascope 85 T/
FL with Zeiss Photoadapter (left) does
provide one magnication (right).

Use with Binoviewers
The Hyperion Universal Zoom Mark IV has an outermost diameter of just 55 mm,
which makes it a perfect choice for bino-viewers. People of all ages, even children
with an interpupillary distance of just 55 mm, can use a binoviewer with two Mark
IV Zoom-eyepieces – a big advantage e.g. for public observatories. The click-stops
greatly eases the quick change of magnication without even having to look at the
eyepiece scales.
By removing the height-adjustable eyecup, a huge gain in “nose space” is achieved.
The stepped eye-piece housing offers the dearly needed space for your nose, such it
becomes much easier to nd the best viewing position to observe comfortably with two
eyepieces side by side. By choosing the winged eyecups instead of the height-adjust-
able ones, even wearers of glasses can observe comfortably with both eyes.
Note: we recommend the shorter adapter ring „A“
(for spotting scopes) also for observations with
bino-viewers, together with the 1¼" nosepiece. You
will gain ~4 mm of optical length compared to
using the adapter ring „B“ (for telescopes). Ob-
serving with any binoviewer regularly forces
the user to ght for every mm of back-fo-
cus in order to achieve a focused image,
just like when using a spotting scope.
The optional Hyperion Zoom Barlow Lens – 2,25x (#2956180)
The 2.25x Baader Hyperion Zoom Barlow lens was
designed especially to complement the Hyperion Zoom
eyepiece. It converts the regular focal lengths of 8 to 24
mm to a range of focal lengths between 3,6 and 10,7 mm,
while retaining the outstanding image quality for observing
sun, moon, planets and double stars with high resolution.
The Mark IV Zoom, in conjunction with or without the Hyper-
ion Barlow, covers all focal lengths between 3.6 to 24 mm.
The Hyperion Barlow works with every Hyperion 8-24 mm
Zoom eyepiece ever produced. The barlow is attached
onto the 1¼"-nosepiece. Because of the dual nosepiece
of the Mark IV, it can be used at telescopes with 1¼" or 2"
eyepiece clamps.
The pictures above show the Universal Zoom Mark IV
eyepiece together with the barlow, on the left for 1¼" and
on the right for 2" eyepiece clamps.
The Hyperion Barlow comes with a T-2
thread-adapter, to mount the Barlow in front of
any camera or other accessories with T-2-threads.
Combine it e.g. with a DSLR-camera – in this way
the camera body will be equipped with a 1 ¼"
nosepiece. The camera body just needs a stan-
dard T-ring to t it onto any 1 ¼” eyepiece holder.
www.baader-planetarium.com/en/camera-adapter
Attach the lens unit without the Barlow-adapter
(A) directly onto many 1¼" eyepieces, whenever
they do not already have an integrated barlow
element. The result is a 2x Barlow with very good
optical properties (see left image).
Some highlights of the Hyperion Zoom Barlow Lens:
• Triplet lens for highest optical quality
• Anastigmatic Flateld Design for high sharpness all over the eld of view
• Baader Phantom CoatingTM Group for highest contrast and light transmission
Mounting at the eyepiece side:
• T-2 (M42x0,75mm) thread with Barlow-Adapter (B)
• Direct connection to any Hyperion Zoom eyepiece with Bar-
low-Adapter (A)
• 1¼" Filter thread without additional adapter
Please note:
The Barlow element can only be used with telescopes,
not with spotting scopes!
