Your Perfect Solution for Crisp, Immersive Views
The Baader Planetarium Hyperion 72 degree Aspheric Eyepieces offer top-tier performance and unique photo-visual features at an incredible price. Versatile and built with quality in mind, these Baader instruments are a must have within your observing toolkit. Read on as we take a deeper look at the outstanding features offered!
Outstanding Optical Quality
Unlike the optics on the Baader Hyperion eyepieces, subpar optics often result in blurry, lackluster detail near the edges of the lens. This is due to near-edge rays refracted towards the center. An aspherical optical design, as seen on these Baader eyepieces, correct for this issue, delivering sharpness across the entire 72° field of view. Bolstering clarity, these lenses are fitted with the advanced Hyperion Phantom Group multi-coatings specially designed for the Hyperion eyepieces. This optimized coating technology means fainter stars and a darker background sky, helping you observe the night sky with outstanding detail!
36 mm Focal Length
This Baader Planetarium Hyperion Aspheric 72° eyepiece boasts 36 mm of focal length. The ratio of telescope focal length and eyepiece focal length (i.e. your system’s magnification), will help you determine which celestial objects could be viewed and how clear your overall image will be based on your local seeing conditions. To calculate magnification, take your telescope focal length and divide it by your eyepiece focal length. A standard 1200 mm focal length Dobsonian paired with this 36 mm Hyperion eyepiece will yield a magnification of ~33x, a happy middle-ground for viewing a wide variety of large deep space objects across almost all levels of seeing!

Compatible with both 2” and 1.25” Focusers
The Baader Hyperion Aspheric 72° eyepieces offer use with both 1.25” and 2” focusers. Each eyepiece package includes a 1.25” and 2” plug-in sleeve for seamless attachment to just about any system. If you have a Schmidt Cassegrain telescope, the telescope side of this Baader Hyperion Aspheric eyepiece can be screwed directly to the end of your SCT (without a plug-in sleeve attached). This direct connection results in the highest rigidity possible for your projection imaging system.
Precision Engineered
Constructed with a sleek precision-machined body and soft, folding rubber eyecups, this Baader Planetarium Modular 72° eyepiece is built with the utmost quality in mind. Each Hyperion comes with protective lens caps to keep your eyepiece safe when not in use. The inclusion of interior baffling eliminates stray light and ghost reflections for maximum clarity. Additionally, the broad upper housing and tactile rubber grip provides secure handling even with gloves on.
Great for Binoviewing!
The Baader Hyperion Aspheric 72° eyepieces are a standout choice for binoviewing. When compared to some wide field eyepieces developed especially for binoviewing, the Hyperions were superior in every aspect: more comfortable view with better eye relief, smaller housing diameter at the eyelens gives more nose-room, better coatings for better contrast, a wider field, and half the cost. These eyepieces can be used with just about any telescopic binocular with an eye distance greater than 56 mm.
An Ideal Projection Eyepiece
Ready for streamlined eyepiece projection imaging? With the built-in threads on the top of this Baader Hyperion 72° Aspheric Eyepiece, attaching your camera is a breeze. Simply remove the rubber eyecup and thread-protecting silicon ring to expose the M43 or SP54 threads. The extensive number of Baader adapters and Hyperion Digital T-Rings enable coupling to just about any camera, DSLRs, small webcam-like cameras, and even some video-cameras for a host of applications. Take a look at this comprehensive guide on digiscoping with your Baader Planetarium 36 mm 72° Modular Eyepiece, diving into the various connection methods available!
Understanding Exit Pupil
The exit pupil of your eyepiece is the diameter of the beam of light exiting your eyepiece, and it’s an important factor in determining how bright your image will be and what objects are best suited for observation. We measure the exit pupil by its diameter in millimeters, with the bigger the diameter, the brighter the image. Exit pupil is calculated with the following equations: Exit Pupil = Telescope Aperture (mm) ÷ Magnification, or Exit Pupil = Eyepiece Focal Length ÷ Telescope Focal Ratio. Large (5-7 mm) and medium (2-5 mm) exit pupils are wonderful for deep sky objects. Small exit pupils, on the other hand, perform well for small, bright objects like the planets or the lunar craters. This Baader Planetarium Hyperion eyepiece has a focal length of 36 mm. A standard f/6 telescope paired with this eyepiece will yield an exit pupil of 6 mm, a great choice for observing faint galaxies, nebulae, star clusters, and more!
