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 fits
directly onto the Mark IV. This SP54 adapter is the base to adapt the Mark IV onto all
common camera lenses with a filter 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 filter 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

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 filter 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.

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 magnification.
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 flat field 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 magnification 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 fixed magnification). However - the Mark IV will provide a
wide range of magnification.
Example:
The Zeiss Diascope 85 T/
FL with Zeiss Photoadapter (left) does
provide one magnification (right).
