Quality Crafted & Designed for Crisp, Immersive Views
The Baader Planetarium Hyperion 68 degree 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
The Baader Hyperion 68° Eyepieces are constructed with high grade water-white glass for crystal-clear views with minimal scatter. The internal lenses present exceptional color correction free from the yellow or bluish tint seen on other, lower quality eyepieces. The high-index glass elements deliver low distortion and astigmatism, even on scopes as fast as f/4. 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!
24 mm Focal Length
This Baader Planetarium Hyperion Non-Variable 68° eyepiece boasts 24 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 24 mm Hyperion eyepiece will yield a magnification of 50x, a happy middle-ground for viewing a wide variety of large deep space objects across almost all levels of seeing! To take a deeper dive within this topic, take a look at our Ultimate Telescope Eyepiece Guide found within our Astronomy Hub.
Please Note: The 24 mm Hyperion is a different optical design and does not permit the use of Finetuning Rings nor houses a removable first lens group to alter the focal length.
Compatible with both 2” and 1.25” Focusers
The innovative design of the Baader Hyperion 68° eyepieces offer use with both 1.25” and 2” focusers. The bottom 1.25” barrel adapts seamlessly with smaller scopes and more compact diagonals, while the full-length (0.94" long) 2” barrel built into the housing of this eyepiece opens the doors for use with larger equipment. As a helpful add-on, the Baader Hyperion 2" Finetuning Stop Ring (not included) prevents the 1.25" eyepiece barrel from damaging your diagonal’s mirror or prism by putting a hard stop on its sitting position.
Precision Engineered
Constructed with a sleek precision-machined body, hard anodizing, and soft, folding rubber eyecups, this Baader Planetarium 68° 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 careful opto-mechanical design and inclusion of interior baffling eliminates stray light and ghost reflections for maximum clarity. Within the eyelens is a pitch black interior to further dampen unwanted stray light. Additionally, the broad upper housing and tactile rubber grip provides secure handling even with gloves on.
Great for Binoviewing!
The Baader Hyperion 68° 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. In addition, the Hyperion field stop locations have been re-designed and optimized to give the shortest focus position possible, a feature incredibly useful for binoviewer use.
An Ideal Projection Eyepiece
Ready for streamlined eyepiece projection imaging? With the built-in threads on the top of this Baader Hyperion 68° 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 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 24 mm 68° 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 24 mm. A standard f/6 telescope paired with this eyepiece will yield an exit pupil of 4 mm, a great choice for observing faint galaxies, nebulae, star clusters, and more!
Frequently Asked Questions
What can I see with the Baader Hyperion 68° 24 mm Modular Eyepiece?
Boasting a focal length of 24 mm, this medium powered eyepiece is wonderful for getting up close and personal with larger deep sky targets. For instance, pairing this 24 mm eyepiece with a 1200 mm focal length telescope will yield a magnification of 50x. This is a great rate for observing the Orion Nebula, the Pleiades Star Cluster, the entire Triangulum Galaxy, and plenty more!
Is the Baader Hyperion 24 mm 68° eyepiece modular? Can I change the focal length of this eyepiece?
Unlike the other models within this Baader Hyperion series, this 24 mm eyepiece is not modular in design. The first lens group is fixed on the eyepiece and this unit does not accept finetuning rings for focal length adjustment.
How do I attach my camera to my Baader Hyperion eyepiece?
These Hyperion Modular eyepieces house M43 and SP54 threads underneath the protective silicon ring atop the eyepiece. Baader offers a wide variety of adapters to adjoin your camera to these threads for projection photography. While determining which adapters needed depends on your specific setup, this comprehensive guide on digiscoping with your Hyperion eyepiece goes in depth on the various connection methods available!
How do I calculate magnification?
Magnification can be calculated by taking your telescope’s focal length and dividing it by your eyepiece’s focal length. For instance, if we have an 8” 1,200 mm focal length Dobsonian telescope, and we’re using the Baader Hyperion Modular 24 mm eyepiece, the magnification will be as follows: 1200/24 = ~50x. It’s important to note that magnification influences how bright your image will be, as the higher magnification, the dimmer your image will become (when using the same aperture). Be sure to check out our Ultimate Telescope Eyepiece Guide for more on this topic!
What’s the difference between apparent field of view (AFOV) and true field of view (TFOV)?
Apparent field of view refers to how large the image is to your eye. For reference, a single bare human eye has a field of view of approximately 150°. These Apertura Panorama eyepieces offer an 82° AFOV for a well-immersed experience. True field of view, on the other hand, refers to the angular diameter of the “chunk” of the sky you are observing. TFOV is determined by dividing your AFOV by your system’s magnification. For instance, an 8” 1,200 mm focal length Dobsonian paired with this Baader 24 mm 68° Hyperion eyepiece will yield a TFOV of 1.36°. The full disk of the Moon, for example, has an angular diameter of 0.5°. For more on this topic, our comprehensive Ultimate Telescope Guide provides an in-depth look!
