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 magnication
because they were designed with focus on the price-tag
so that image sharpness and eld size are getting worse
with increased magnication.
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-
ni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 high-
est magnication.
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.

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 modied to improve operation at cold temperatures and the parfo-
calty 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. 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 innity 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° eld of view at highest magnication, 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 magnication 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 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 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.

Eyecups
Three different eyecups are included with the Mark IV Zoom.
Choose the eyecup according to your preferences or desired eye
relief (with or without glasses):
The Zoom-eyepiece with
the winged eyecup.
The height of the large eyecup
can be adjusted.
The Universal-Zoom
eyepiece with the
round, foldable eyecup.

1. The standard eyecup is the large height-adjustable eyecup that
also fastens onto the M43 photo-thread of the eyepiece. By ro-
tating 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. This
eyecup is preinstalled when the eyepiece is shipped and the
most common eyecup for use with a telescope
2. A folding rubber eyecup alternatively ts straight onto the
M43-thread. This is the preferred solution for observers with-
out glasses at a binoviewer. It gives you enough room for your
nose, at the same time it provides 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 eye-
piece eld of view. This helps to concentrate on the target when
using a binoviewer.
In case of need an optional, 7.5 mm long 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 photo/video-thread is
located on the top of the eyepiece.

Telescope-Adapter B
Locking Ring
Changing the mounting adapters A and B
In the standard conguration, both 1¼" and 2" nosepieces are mounted at the eyepiece
main body, including dustcaps. Remove both dust caps before using the eyepiece 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 1:
Hold the eyepiece at the locking ring 3, which also
has a 2" female thread inside, and unthread the
nosepiece counterclockwise. Now you can access
the 1¼" nosepiece, 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 telescopes, prisms and mirrors with male
2"-SC-thread.
2. Removing the 1¼" nosepiece 2:
Remove the nosepiece by rotating it counterclock-
wise. Now you can see the 13 /
8" thread of the tele-
scope-adapter B 4(or of the spotting-scope-adapter
A), and you can screw the eyepiece directly onto
many smaller spotting scopes (e.g. Celestron Ultima,
Skywatcher).
3. Replacing the adapterring for telescopes (B) 4
or spotting scopes (A) 5:
Completely unscrew the knurled 2" locking ring 3
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“).

8Instruction Manual: Hyperion®Zoom Mark IV
Telescope-sided connection options
There are three different ways to adapt the Hyperion®Universal Zoom Mark IV onto a
telescope. You can change between the three modes easily within seconds.
2" Eyepiece Barrel
(intended for 2" star diagonals):
The nosepieces for 2" and 1¼" are both
pre-mounted. The eyepiece ts "out-of-the-box"
into 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.
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 the eyepiece lock-
ing screws of the star diagonal (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
threaded into the 1¼" 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 Schmidt-Cassegrain thread can be utilized as soon as
the 2" nosepiece is 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 back-
end thread of SC-telescopes and their derivatives. Alternatively 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 adaptation and saves
about 45 mm of optical length (the closer distance
even results in a slightly larger eld of view, in
case you are using a Schmidt-Cassegrain optics).
Filters
The Mark IV zoom eyepiece allows you to use
both 1.25" and 2" lters because each of the two
nosepieces has got a lter thread. So you can
also use 1.25" lters when using the eyepiece on
a 2" eyepiece clamp. Please note that for space
reasons it is not possible to use both 1.25" and
2" lters at the same time.
Filters cannot be used on spotting scopes either.
This would make the overall length too long, and
the spotting scope could no longer be focused to innity.
Connection options for spotting scopes
Spotting scopes with integrated 1¼" eyepiece
These spotting scopes in most cas-
es 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 re-
place the telescope adapter „B“ against the spotting scope adapter „A“, as described
on page 5, to gain almost 4 mm in backfocus compared 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 Hum-
mingbird or TrailSeeker (image).

10 Instruction Manual: Hyperion®Zoom Mark IV
Kowa STN 770/880 Spotting Scopes
You also have two options for use with Kowa spotting scopes.
For a screw connection you need the short Hyperion®Mark IV
Zoom to M54 Kowa TSN 770 / 880 Adapter # 2454836. It allows
the connection of the Mark IV to KOWA spotting scope with male
M54 thread. The adapter replaces the 2" coupling nut and offers
a larger back focus reserve so that you can focus more easily to
innity. This solution is particularly suitable if you wear glasses.
Further information can be found in the product description of the
adapter.
Alternatively, the Mark IV, like many other astronomical eyepieces,
can be used with the 1¼" / M41 eyepiece adapter for Kowa TSN
770 / 880 Spotting Scopes # 2454520 on corresponding Kowa
spotting scopes. The adapter is pushed over the 1.25" nosepiece
and fastened. Use the short scope adapter "A". For more informa-
tion, see the product description of the adapter.
Zeiss Diascope Adapter
# 2454500
Zeiss-Diascope Spotting Scopes
You have two options for use with Zeiss Diascope spotting scope. For
a screw connection you need the short Zeiss-Diascope/Mark IV Zoom
Adapter #2454831 (right). It offers a larger back focus so that you can
focus more easily on innity. This solution is particularly suitable for spec-
tacle wearers. It is simply attached with the coupling
nut to which the 2" sleeve is attached. For more infor-
mation, see the product description of the adapter.
Alternatively, you can use the optional Zeiss-Dias-
cope Bayonet Adapter 1¼" #2454500 (left). Cong-
ure the eyepiece as described above with the Spot-
ting Scope Adapter A and the 1¼" nosepiece, then
fasten the Bayonet Adapter on the 1¼" nosepiece.
The diascope-adapter
# 2454831 is clamped
with the locking-ring
Spotting Scopes with 13 /
8" male thread
Such spotting scopes (e.g. many Skywatcher,
Orion, Acuter, Synta and Celestron spotting
scopes) can be used directly with the Hyperi-
on®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 spot-
ting scope.
This way a very short adaptation onto the
spotting scope is achieved – ensuring to
reach innity focus.

Zero-Length-Adapters
The telescope adapter "B" or the spotting scope adapter "A" can be replaced by one
of the following zero length adapters, which are not included in the scope of delivery.
This allows additional threads to be retrotted to adapt the eyepiece to other spotting
scopes. The following zero-length thread reducing rings (without optical length) are
currently available:
• 2"a / M41.5i # 2454832 – suitable for adaptation to Bausch & Lomb, Opticron and
Kowa basic spotting scopes with male M41.5 x 1 connection thread
• 2"a / T-2i # 2454833 – suitable for adaptation of any accessory with male T-2 con-
nection thread (e.g. for connection to our VariLock 20-29 or VariLock 29-46 clamps)
• 2 "a / M48i # 2454834 – manufactured to adapt to any photographic M48 x 0.75
thread (the 2" astronomical lter thread)
• 2 "a / M44i x 1 # 2454835 – suitable for adaptation to Leica spotting scope with
male M44 x 1 connection thread. Also suitable for all M44x1 threads according to
the old Zeiss (Jena) standard.
The connection is the same as for the short Zeiss-Diascope/Mark IV Zoom Adapter
#2454831; for some spotting scopes, however, the protective sleeve that encloses the
zoom mechanism under the 1.25" sleeve must be removed. Be careful and only remove it
if really necessary. For more information, refer to the product description of the adapter.
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

12 Instruction Manual: Hyperion®Zoom Mark IV
24mm focal length 20mm focal length 16mm focal length 12mm focal length 08mm focal length
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:
Example: The Zeiss Diascope 85 T/
FL with Zeiss Photoadapter (left) does
provide one magnication (right).
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 adapter. 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 can be aligned to the
horizon easily after zooming (it rotates with the zoom mechanism), or you can 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 15 mm # 1508154, T-2 extension tube 7,5 mm # 1508155
~ 40 mm optical length
• Alternatively: M43/T-2 Adapter # 2958080, extension tube 40 mm # 1508153
~ 41,5 mm optical length
For APS-C:
• M43/T-2 Adapter # 2958080, TQC/TCR Quick Changing System # 2456322,
T-2 extension tube 15 mm # 1508154
~ 32,5 mm optical length
• Alternatively: M43/T-2 Adapter # 2958080, 2x T-2 extension tube 15 mm # 1508154
~ 31,5 mm 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-adapter 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.

Attaching camera-lenses by their front-lens filter threads
Most camera lenses attach onto the Mark IV (or any Hyperion®or Morpheus®eye-
piece) 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 camera for afocal projection imaging.
The SP 54 step-rings for making this system most versatile are called „Hyperion®D T-
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 camera-
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 dis-
tance between eyepiece and camera front lens. This is crucial to reduce
or completely avoid vignetting. The M62-ring can even serve as base for
larger Hyperion® 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 Exten-
sion 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 cam-
era lens and Mark IV completely to avoid damage to your valuable camera lenses.
Digiscoping-overview
There are numerous possible combinations for attaching
a camera and many things to consider. Under the name
digiscoping, this technique is also popular with animal lovers
today, who take pictures with a spotting scope and do not
need an additional, heavy telephoto lens.
All important combinations and the formulas for calculating
the achievable focal lengths can be found in our Digiscoping
brochure. You can obtain it from your specialist dealer or as a
PDF under www.baader-planetarium.com/en/digiscoping

14 Instruction Manual: Hyperion®Zoom Mark IV
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 interpu-
pillary 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 ease 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-adjustable ones,
even wearers of glasses can observe comfort-
ably with both eyes.
Space for your nose
– and a comfortable
viewing behaviour
# 2454610
# 2456460
Note: we recommend the short-
er adapter ring „A“ (for spotting
scopes) also for observations
with bino-viewers, together with
the 1¼" nosepiece. You will gain
about 4 mm of optical length com-
pared to using the adapter ring
„B“ (for telescopes). Observing
with any binoviewer regularly forc-
es the user to ght for every mm
of back-focus in order to achieve
a focused image, just like when
using a spotting scope.

Important Mark IV Zoom accessories
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 Hyperi-
on®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 eye-
piece 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-adapt-
er, 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 standard T-ring to t it onto any 1 ¼” eyepiece
clamp.

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 proper-
ties (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 Barlow-Adapter (A)
• 1¼" Filter thread without additional adapter
Please note:
The Barlow element can only be used with telescopes, not with spotting scopes!
