Baader Morpheus Optical Features
Full Field Sharpness: The sharp flat 76° field of the Morpheus is unsurpassed by any other modern wide field eyepiece. On-axis sharpness and contrast rivals Baader’s best planetary eyepieces, while delivering nearly equivalent performance over the full field. Stars remain diamond pinpoints as you move away from center, and the field remains flat and in focus, even in short focus telescopes.
Long Eye Relief: The Baader Morpheus pushes the envelope of comfortable wide field viewing further than ever before, delivering 23mm of eye relief along with best-in-class optical performance. Eyeglass wearers can comfortably take in the full field, and binoviewer users will find that the Morpheus series is the ultimate companion for viewing with two eyes.
Low Distortion: The Morpheus optical design delivers exceedingly low distortion (angular magnification distortion). Planets and lunar features retain their shapes as they transit the field and the true field sizes are close to theoretical. Many companies exaggerate at this point and deliberately use off-axis distortion magnification as a means to advertise blown "apparent" field sizes. You will be able to compare this given field size of 76° and find it to be the true value (apparent view angle as seen by the observer's eye).
Immersive Views: As avid observers themselves, the folks at Baader have studied the behaviors of most commonly available wide field eyepieces and listened to comments from other observers regarding the eyepieces they believe give the most palpable and engaging wide field viewing experience. What they found is that the subjective ‘spacewalk’ feeling is not just a function of field of view. Interestingly, some wide-field eyepieces with fields of 82 degrees failed to deliver the same viewing experience as others with similar fields, or even some with smaller fields. It was discovered that two additional primary factors played into the equation – Eye Relief (and the related large eye lens size) and Ease of Viewing (a combination of long eye relief and control of pupil aberrations). It was also found that fields much below 74 degrees tended to have a reduced effect. So, with this information in hand, Baader set out to design a new eyepiece with a field of view greater than 74° that met all of the other optical parameters necessary to deliver a truly "immersive" viewing experience where the eyepiece essentially disappears. The result is Morpheus®.
Phantom Coating® Group: Pioneered in the Hyperion lineup, the Phantom Group Multi-coatings have been further optimized for use in the Morpheus and index-matched to each of the different glasses.
Optimized Internal Baffling: As with all Baader Planetarium eyepieces, the internal mechanicals have been fully ray-traced and baffled to eliminate the effects of stray-light.
Baader Morpheus Mechanical Features
Optimized for Binoviewing: Every last bit of space has been squeezed out of the main body to minimize its size, giving maximum nose clearance for binoviewing.
Weight reduction: Every effort has been made to eliminate unnecessary weight - especially in view of effective binoviewing.
Foldable Eyecups: The Morpheus includes two soft rubber dual-position foldable eyeguards. These innovative eye cups have been developed to provide the optimal comfort and eye spacing for most users and eye glass wearers. The included special winged version provides the ultimate comfort and exclusion of stray light necessary for binoviewing with eyeglasses.
Safety Features: The 1.25” and 2" barrels of each Morpheus eyepiece incorporate Slip-Protect Safety Kerfs; the ideal safety compromise between smooth barrels and wide undercuts. The numerous shallow kerfs give additional grip and security from inadvertent drops from smooth sided barrels, without the annoying problems sometimes caused by traditional wide undercuts. A wide waffle-patterned rubber grip ring gives an extra measure of handling security.
Long lasting Photo-Luminescent Engraving: Over-sized, glow-in-the-dark engraving of the focal length makes it easy to choose the proper eyepiece without the need for a flashlight.
Photo-Video Adaptation: Like their Hyperion siblings, all Morpheus eyepieces make superb imaging projection optics. Each Morpheus includes a hidden M43 photo-video eye lens thread that permits use of Baader’s extensive range of Hyperion Digital T-Rings. These rings permit direct-thread attachment of practically any imaging device for the ultimate in rigidity and close-coupling for minimal vignetting.
