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 retrofitted 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 filter 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
