68° Apparent Field, Long Eye-relief, Incredibly versatile eyepiece..
1.25 diameter fits all scopes. One of the very Best Values in eyepieces.
13mm Focal Length
1.25" or 2" compatible
68° Apparent Field
S54 and T43 camera adapter threads incorporated into body
Eyepiece produces focal lengths of 22.9mm, 13mm, 10.8mm (14mm FT ring), 9.2mm (28mm FT ring), and 8.1mm (14+28mm FT rings)
Optimal 68° apparent field of view, the largest accessible to the
stationary human eye. The entire field remains visible despite the slight
involuntary motions of an observer’s head that simply can’t be avoided.
The annoying "kidney bean effect”, the bane of many ultra wide-field
eyepiece designs, is completely absent in the Hyperion.
8 lens elements in 5 groups provide outstanding sharpness and color
correction over the entire field.
Comfortable eye relief of 20 millimeters.
No vignetting or falloff of illumination near the edge of the field.
The use of high-index glasses results in minimal distortion and
Unsurpassed color fidelity. Many eyepieces that employ cheaper glasses
or inferior designs impart a yellow or blue cast to the image. With Hyperion
eyepieces white stays white!
The most advanced anti-reflection multicoatings are employed on all
ten air to glass surfaces for maximum light throughput and brilliant images.
All coatings are carefully matched to the index of refraction for each of
the different glass substrates used.
The painstaking design and execution of baffling has all but
eliminated troublesome stray light and ghost reflections. Don’t take our
word for it – test it for yourself! Put a Hyperion eyepiece and your own
eyepieces onto a matte black surface and allow a beam of sunlight or an
intense artificial light source to shine into the eyepieces from above.
Looking into the eyepieces from some distance you will note that some
eyepiece interiors will shine milky white with stray light, resulting in a
"flat” image with reduced contrast. Not the Hyperion! Under all conditions
of illumination, the interior of a Hyperion eyepiece will appear jet black,
testimony to the virtual elimination of stray light.
Shortest field stop position of all widefield-eyepieces known to us.
Specifically designed for binocular viewing
Ideal for use with accessory binocular viewers thanks to a tight barrel
diameter (58 millimeters with the removable neoprene rubber grip ring,
56 millimeters with the grip ring removed) that permits interpupillary
distance settings of as little as 56 millimeters, permitting stereo wide views
even for kids.
Each Hyperion eyepiece in the series is actually five eyepieces in one!
Simply by unscrewing the forward 1.25-inch diameter portion of barrel
that houses the negative achromat lens group, will provide a wide-field
eyepiece of much longer focal length. Color correction remains
excellent, and the field curvature that results is no greater than in a decent
specimen of the 6-element Erfle design (and that’s what it is actually, when
the negative achromat is removed). Additional Fine Tuning Rings of 14mm and 28mm
can be inserted between the upper and lower barrels to produce 3 additional (higher)
Removing the negative lens group exposes an M 48 female thread
at the end of the 2-inch diameter barrel of the long focal length component
so that large-format light pollution and nebular filters can be employed.
Thanks to the short 1.25 chrome sleeve of 0.94”, all Hyperion’s are
principally compatible with spotting scopes, including high-end
units by Leica, Swarovski, and Zeiss.
The multi-functional Baader Hyperion 68° Modular Eyepieces
Much more than just another eyepiece!
Perfectly suited for afocal projection imaging with the help of up to 16 special digital T-rings.
Featuring an auto locking 2” sleeve – capable of securely supporting the
heaviest digital and video cameras.
For afocal projection imaging, the digital camera threads S 54 and
M43 x 0,75 have been incorporated for compatibility with
Series 54 digital T-rings that permit attaching almost any digital and video
camera without vignetting. These threads are protected by rubber caps
when not in use.
The M 43 x 0,75 thread directly screws into many video cameras,
notably the recent 3 CCD-Cameras manufactured by Panasonic.
S 54 digital T-adaptor rings screw directly into the filter thread of most
digital cameras and digital camcorders.
Some camera models equipped with exposed, movable zoom lenses
will require a separate intermediate (filter) adaptor available from the
manufacturer. However, the vast majority of large digital cameras and
camcorders of recent vintage feature an internal zoom lens with a fixed
front lens and standard filter threads.
The robust construction of Hyperion eyepieces is capable of directly
supporting heavy video and film cameras weighing up to 3 kilograms.
Hyperion eyepieces are also ideal for use with so-called clamping-style
universal digital camera holders,
and will precisely support cameras squarely with respect to the optical
axis, due to their straightforward cylindrical shaped outer body.
With or without the removable negative lens group, the Hyperion
eyepiece is an incredibly sharp projection system.
In combination with a short-focus objective as small as 60mm aperture,
the same afocal imaging configuration can be employed in industry for
monitoring hazardous operations like plasma welding from a safe distance
13mm Focal length
Fits 1.25" and 2" focusers
Accepts 1.25" and 2" filters
Accepts 43mm and 54mm T2 photographic adapters for eyepiece projection
20mm eye relief--perfect for glasses wearers.
Includes rubber eyecup, caps for top and bottom, and stash bag for safe storage.
Other focal lengths can be created by using the Fine Tuning Rings.
