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 fits "out-of-the-box"
into 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.
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 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 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" filters will work in this configuration 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"
