Baader Morpheus 76° wide-angle eyepiece 1¼ / 2" focal length 12,5 mm

BAADER Morpheus® 76° wide-angle eyepieces
Visual/photo and video - high-end for your telescope
The eyepiece is half the optics of a telescope - if you really want to make the most of your telescope, good mid-range eyepieces reach their limits. The Morpheus® eyepieces offer a sharp image right to the edge of the 76° field of view. The brightness and richness of contrast open up a new dimension in eyepiece construction. These eight-lens eyepieces with Phantom Coating® Group are just as impressive for planetary observation as they are for deep-sky objects - even as a photographic projector.

The Morpheus® wide-angle eyepieces with a focal length of 4.5 to 17.5 mm are the perfect complement to your overview eyepieces: Even at the high magnifications, they each provide a larger, excellent overview of the sky than is claimed for many other eyepieces with a field of view of over 80 degrees. You can see your target objects wonderfully embedded in the stellar surroundings. In addition, the large field of (Dobsonian) telescopes allows you to take much more time when changing eyepieces without tracking. All Morpheus® eyepieces have 1.25" and 2" receptacles with Safety-Kerf locking grooves. On (Newtonian) telescopes with a low focus position, this makes a 2"/1¼" reducer unnecessary, as the 2" receptacle integrated into the eyepiece body saves approx. 21 mm of focus travel.

There are no better eyepieces for observation with a binoviewer that have been designed so consistently for use with a binoviewer while maintaining the same field angle, avoiding vignetting and due to their shape and low weight. The built-in lenses are extremely large in relation to the slim outer diameter, so that a comfortable view is guaranteed even at very close interpupillary distance with a binoviewer. You will not find an eyepiece with a comparable "space-float effect". With binocular viewing, the edge of the field of view seems to disappear and you feel like you are floating in space. The field of view becomes visible even if the distance between the eyes is too great. This is a coveted eyepiece feature, especially at public observatories, in order to offer inexperienced visitors a safe observation experience.

Just like the modular Hyperion® eyepiece series with 68° field of view, the 76° Morpheus® eyepiece series is also particularly suitable for photography, partly because the distortion is considerably less than with the Hyperion® eyepieces despite the larger field angle. The M43/T-2 photo/video adapter #2958080 also fits all Morpheus® eyepieces. With this optional M43/T-2 connection ring, you can use practically any DSLR or system camera for classic eyepiece projection via the globally established system of T-2 bayonet rings and attach the eyepiece in front of the camera at the correct projection distance instead of a Lens. For so-called afocal eyepiece projection, an M43/SP54 extension ring is available, with the help of which any Morpheus® eyepiece can be mounted so close to the lens of a large camera lens using the Baader SP54 adapter rings that both lens surfaces almost touch. It is precisely this precise distance control that ensures good illumination of the camera sensor in afocal projection.

Optical properties

• Sharp stars right to the edge: The 76° field of view is unsurpassed by any other modern wide-angle eyepiece in terms of sharpness across the entire flat field. On-axis sharpness and contrast match the optical performance of Zeiss Abbe II eyepieces, but over a dramatically larger field of view. Even with fast telescopes, the stars remain pin-sharp even at great distances from the center of the image, without disturbing field curvature
• Long eye relief: With the Morpheus® you can observe more comfortably than ever before with wide-field eyepieces - they combine almost 20mm eye relief with the best optical performance in their class. Eyeglass wearers can see the entire field of view, and at the binocular attachment you can enjoy the ultimate viewing experience with the Morpheus®.
• Minimal distortion: The very elaborate design of the Morpheus® enables exceptionally low angular distortion. This means that the moon and planets are not distorted as they move through the field of view, and the fields of view really do correspond to the theoretically calculated value. Many manufacturers like to exaggerate the apparent field of view and use the edge distortion constructively in order to be able to claim a large "apparent" field of view in advertising. You will see that the view really matches what the focal length and field of view suggest.
• Spacewalk feeling: We tested numerous eyepiece types ourselves and listened to the wishes and impressions of other observers. We noticed that the requirements for wide-angle eyepieces cannot be reduced to the field of view alone. The immersion in the universe - the "spacewalk" feeling - does not occur equally with all eyepieces. Some 82° eyepieces have a constricting effect, while with others - sometimes even with a smaller field of view! - you have the feeling of being directly between the stars. We have found that two other factors play a role: Interpupillary distance (for which the greatly enlarged eye lens of the Morpheus® is absolutely necessary) and a comfortable viewing behavior without "kidney bean effect" (this results as a combination of large interpupillary distance and an optical construction tolerant to involuntary pupil movement). However, we also realized that this spacewalk effect no longer occurs at well below 74° field of view, because the field of view limitation then becomes too perceptible. With this knowledge, we developed the Morpheus® eyepiece with a 76° field of view, which fulfills all the necessary requirements to enable a real spacewalk feeling without the disturbing edge of the field of view. Especially when used with binocular approaches, you have the feeling of being completely immersed in the action.
• Phantom Coating® Group: The Phantom Group multi-coating introduced with the Hyperion® eyepieces has been further optimized for the Morpheus® eyepieces and adapted to the different types of glass.
• Optimized apertures: Like all Baader Planetarium eyepieces, the internal diaphragms have been optimized by ray tracing to eliminate stray light and reflex effect.

Mechanical properties

• Optimized for binoviewers: The Body has been deliberately kept slim so that it offers every "nose shape" sufficient space for binocular observation.
• Lightweight construction: The eyepieces have been designed to be stable and at the same time weight-saving, not least for use with binoviewers. The heaviest parts of the Morpheus® are the lens groups; the waterproof body is designed to be as lightweight as possible.
• Fold-downeyecups: A metal ring with an M43 thread is incorporated into the fold-down eyecup. This enables a soft and supple eyecup that can also be firmly screwed to the eyepiece. The second eyecup has a side light shield as stray light protection and is primarily intended for use with binoculars. Both have been designed to provide optimum comfort and eye relief for most observers - including spectacle wearers - and protect the M43 thread described overleaf. The M43 extension is used for extended eye relief adjustment as well as for connecting cameras with M43 threads.
• Safety features: The 1¼" and 2" receptacles are equipped with the Baader "Safety-Kerf" anti-slip device. This creates a perfect compromise between smooth receptacles and the hooky, wide safety grooves. The many small notches form many holding points when smooth eyepieces already start to slip, and at the same time avoid problems such as tilting of the eyepiece, which can occur with an unfortunately placed locking groove. When you pick up the eyepieces, the large rubber ring with waffle structure provides a secure grip.
• Luminescent lettering: The lettering glows a soft green when the eyepiece has been in the light for some time or the lettering has been directly illuminated with a flashlight, for example. This allows you to immediately recognize which focal length you are holding at night.
• Belt holster: The holster case with loop protects the eyepiece and can be used as a belt pouch or attached to a tripod.
• Photo/video adaptation: Just like the Hyperion® eyepieces, the Morpheus® are excellent projection eyepieces for photography. Each Morpheus® has a hidden M43 thread for connecting the Baader Hyperion® Digital T-Rings using our M43/T-2 adapter. This means that practically any better camera can be screwed directly to the eyepiece, very stably and, if necessary, with a minimum distance to avoid vignetting.
