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 fit 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).
