of standard kit eyepieces. Its modular design incorporates both 1.25\" and 2\" barrels for universal telescope compatibility and features integrated M43 and SP54 threads for direct camera attachment. The optical system uses a 7-layer Phantom Group multi-coating optimized for peak light transmission around 520nm, ensuring maximum contrast on faint planetary and deep-sky targets.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eA 68° Field of View at 8mm: High Power, Wide Context\u003c\/h3\u003e\n      \u003cp\u003eThe 8mm focal length delivers high power, ideal for resolving fine detail on Jupiter's cloud bands, splitting tight double stars, or examining the cores of globular clusters. Unlike traditional high-power eyepieces with restrictive views, the Hyperion's 68° apparent field of view provides a wide, comfortable window that keeps objects in sight longer in non-driven scopes and makes manual tracking feel less urgent.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n    \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003ePhantom Group Coatings: 7 Layers for Maximum Contrast\u003c\/h3\u003e\n      \u003cp\u003eBaader's proprietary Phantom Group Coating is a 7-layer broadband anti-reflection system applied to every glass-to-air surface. This coating is specifically engineered to be most effective where the dark-adapted human eye is most sensitive—in the green part of the spectrum around 520nm. The result is a dramatic reduction in scattered light and internal reflections, leading to a darker sky background and visibly higher contrast at the eyepiece.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eTwo Integrated System Threads: M43 and SP54 for Imaging\u003c\/h3\u003e\n      \u003cp\u003eThe Hyperion 8mm is designed for both visual and photographic use. Removing the rubber eyecup reveals two distinct sets of threads for attaching cameras.

This wide view is rendered with exceptional contrast and light transmission thanks to Baader's Phantom Group multi-coatings. These advanced coatings are optimized to be most effective where the night-adapted eye is most sensitive, minimizing reflections across the visual spectrum to deliver brighter images and detect fainter stars.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 10mm Eyepiece with Variable Focal Length Potential\u003c\/h3\u003e\n\u003cp\u003eUnlike conventional eyepieces, the Hyperion 10mm features a modular construction. The front negative lens assembly can be unscrewed from the main body, transforming the eyepiece for different applications.

Its unique dual-barrel design allows it to be used natively in both 1.25\" and 2\" focusers without adapters, offering maximum compatibility. Engineered for both visual and photographic use, the Hyperion 17mm is a flexible optical tool designed to extract high contrast and sharpness from your telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e68° Field with Phantom Group Multi-Coatings\u003c\/h3\u003e\n\u003cp\u003eEvery glass surface in the Hyperion 17mm is treated with Baader's Phantom Group multi-coatings. These advanced coatings are designed to maximize light transmission by minimizing reflections, which is critical for teasing out faint details in deep-sky objects. The coating system is optimized for the peak sensitivity of the night-adapted human eye, resulting in a neutral, color-true image and exceptionally dark sky backgrounds across the entire 68° field.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual-Format Versatility: A 1.25\" and 2\" Eyepiece in One\u003c\/h3\u003e\n\u003cp\u003eThe Hyperion 17mm features a clever mechanical design that incorporates both 1.25\" and 2\" barrels. The 1.25\" barrel, complete with filter threads, is the primary interface. By simply unthreading this section, you reveal a 2\" barrel, allowing the eyepiece to be seated more securely in larger focusers.

Its unique dual-barrel design allows it to be used in both 1.25\" and 2\" focusers, bringing its 21mm focal length and wide-field views to virtually any telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe Hyperion 21mm Optical Design: A 68° Coated Field\u003c\/h3\u003e\n\u003cp\u003eThe Hyperion 21mm is engineered to deliver sharp, high-contrast images across its entire 68° apparent field of view.

This proprietary coating system is optimized to be most effective where the night-adapted human eye has its highest sensitivity.

It functions as a 1.25\" eyepiece out of the box, but by simply unscrewing the lower barrel section, you reveal a 2\" barrel, allowing you to use it in larger focusers without any additional adapters. This provides maximum compatibility across different telescopes.\u003c\/p\u003e\n\u003cp\u003eThis modularity extends to parfocalizing your eyepiece set. With the addition of an optional stop ring, you can precisely set the insertion depth, allowing you to swap between other Hyperion eyepieces with minimal refocusing.

Designed for maximum flexibility, it fits both 1.25\" and 2\" focusers without adapters and features Baader's Phantom Group multi-coatings for superior image contrast.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 24mm, 68° Wide-Field Experience\u003c\/h3\u003e\n\u003cp\u003eWith a 24mm focal length and a 68° apparent field of view, this Hyperion eyepiece provides a generous true field of view that is ideal for locating objects and framing large-scale celestial targets. In a long focal-length Schmidt-Cassegrain or refractor, it functions as a perfect low-power \"finder\" eyepiece, making it easy to scan the Milky Way or fit entire open clusters like the Pleiades (M45) into a single view.\u003c\/p\u003e\n\u003cp\u003eIts clever dual-barrel design allows you to use it as a 1.25\" eyepiece or, by unthreading the lower barrel, as a 2\" eyepiece. This native compatibility ensures a secure fit in any standard focuser or diagonal, providing adaptability for any telescope in your collection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eBaader Phantom Group Coatings for High-Contrast Views\u003c\/h3\u003e\n\u003cp\u003eBaader's proprietary Phantom Group multi-coatings are a key element of the Hyperion's optical system. This advanced multi-layer broadband coating system is engineered to maximize light transmission and minimize reflections across the visual spectrum. The coatings are specifically optimized for the wavelengths where the dark-adapted human eye is most sensitive.\u003c\/p\u003e\n\u003cp\u003eThe result is a view with noticeably higher contrast, suppressed stray light, and natural color fidelity. Unlike eyepieces with less sophisticated coatings that produce a strong green reflection—a sign of lost light—the Phantom Group coatings are nearly colorless, ensuring that the faintest details in nebulae and galaxies reach your eye.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Modular Platform: Adaptable Focal Lengths and Direct Imaging Threads\u003c\/h3\u003e\n\u003cp\u003eThe Hyperion eyepiece is more than a static optical element; it's a modular system. The front lens group can be unthreaded, and with the use of optional fine-tuning rings, the eyepiece's focal length can be modified to achieve different magnifications. This allows you to fine-tune your view without introducing the additional glass of a Barlow lens, preserving maximum sharpness.\u003c\/p\u003e\n\u003cp\u003eFor astrophotographers, the Hyperion line incorporates hidden threads beneath the removable eyecup. These threads provide a secure, direct mechanical connection for cameras, enabling both afocal projection (imaging through the eyepiece) and direct eyepiece projection. This transforms the Hyperion from a visual accessory into a versatile imaging tool.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHyperion 24mm Fixed vs. The Hyperion 8-24mm Zoom\u003c\/h3\u003e\n\u003cp\u003eBaader offers both this 24mm fixed focal length eyepiece and a popular 8-24mm zoom.

observing experience by maintaining a consistent 68° apparent field of view from the high-power 5mm to the wide-field 24mm. This consistency allows you to switch magnifications without the jarring change in immersion that occurs when mixing eyepieces of varying designs, making it easier to frame objects and select the ideal magnification for viewing conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003ePhantom Group Coatings: Optimized for Visual Astronomy\u003c\/h3\u003e\n\u003cp\u003eEach Hyperion eyepiece features Baader's 7-layer Phantom Group multi-coatings. These coatings are engineered to maximize light transmission where the dark-adapted human eye is most sensitive (around 520nm).

Removing the eyeguard reveals both an M43 and an SP54 thread, allowing direct, secure attachment of DSLR and other cameras for high-magnification eyepiece projection photography. While the set provides seven distinct focal lengths, the eyepieces are also designed to work with optional fine-tuning rings (sold separately) to achieve intermediate focal lengths without requiring a Barlow lens, offering a level of system flexibility standard eyepieces lack.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main advantage of the Baader Hyperion 68° set over standard eyepieces?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe primary advantage is the combination of a wide \u003cstrong\u003e68° apparent field of view\u003c\/strong\u003e and high-contrast optics across a full range of focal lengths.

1.25\"\/2\"\u003c\/h2\u003e\n\u003cp\u003eThe Baader Hyperion Universal Zoom Mark IV eyepiece delivers the convenience of a full set of eyepieces in a single barrel, adjusting steplessly from an 8mm to a 24mm focal length. Its optical design provides a wide 68° apparent field of view at the highest 8mm magnification setting and features five positive click-stops at 8, 12, 16, 20, and 24mm for precise, repeatable settings. The redesigned 55mm diameter body weighs only 290g, making the Mark IV an ideal choice for creating a lightweight, perfectly matched pair for binoviewing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAn 8-24mm Zoom Designed for Maximum Sharpness\u003c\/h3\u003e\n\u003cp\u003eUnlike conventional zoom eyepieces that often compromise sharpness at high power, the Hyperion Mark IV was engineered from the opposite perspective. The optical formula, glass selection, and lens polishing were all optimized for the highest magnification setting of 8mm. This ensures that as you zoom in to study fine planetary detail or split tight double stars, the image remains sharp and the apparent field of view expands to a generous 68°.\u003c\/p\u003e\n\u003cp\u003eFeaturing Baader's Phantom Group multicoatings, light transmission is maximized for bright, high-contrast views across the entire zoom range. The result is an eyepiece that defies the typical limitations of zooms, delivering performance that rivals individual fixed-focal-length eyepieces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe Mark IV Redesign: 290g Weight and 55mm Bino-Friendly Body\u003c\/h3\u003e\n\u003cp\u003eThe Mark IV represents a significant mechanical evolution, shedding 80 grams to reach a final weight of just 290g. Its main housing has been slimmed down to a 55mm diameter, allowing a pair to be used in most binoviewers with interpupillary distances as narrow as 55mm. The internal zoom mechanism has also been improved for smoother operation in cold temperatures, while parfocality across the zoom range has been fine-tuned.\u003c\/p\u003e\n\u003cp\u003eFor observers using spotting scopes, the Mark IV offers almost 4mm more back focus than its predecessor, improving compatibility with a wider range of instruments.

The Mark IV refines this with a smoother, yet still positive, click-stop mechanism at five key focal lengths: 8, 12, 16, 20, and 24mm. This allows you to set both eyepieces to the exact same magnification quickly and intuitively, even in complete darkness, eliminating eye strain and ensuring a perfectly merged view.\u003c\/p\u003e\n\u003cp\u003eThree different eyecups are included to optimize comfort and eye placement. For binoviewing, the removable eyecup exposes the M43 thread, allowing the use of winged rubber eyecups that provide maximum \"nose space\" and block stray light, helping you maintain concentration on your target.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Modular System: 1.25\", 2\", and M43 Threads Included\u003c\/h3\u003e\n\u003cp\u003eThe Hyperion Mark IV is a complete viewing system. It ships with both 1.25\" and 2\" barrels, both of which are threaded for standard filters and feature Baader's Zero-Tilt Safety-Kerfs instead of traditional undercuts to ensure a secure fit without wobble. Two dedicated adapters are included: Adapter 'A' for spotting scopes and Adapter 'B' for standard telescope star diagonals, ensuring a flush and secure connection.\u003c\/p\u003e\n\u003cp\u003eOn top of the eyepiece, an M43 thread allows for direct connection of video cameras or DSLRs for afocal imaging.

Barlow\u003c\/h2\u003e\n\u003cp\u003eThis Baader Hyperion Universal Zoom Mark IV set combines the versatile 8-24mm zoom eyepiece with its matched 2.25x Barlow lens, creating a single optical system that covers every focal length from a wide-field 24mm to a high-power planetary 3.6mm. The eyepiece features five positive-action clickstops at 8, 12, 16, 20, and 24mm, while offering a variable apparent field of view that expands to a wide 68° at its highest magnification. With its dual 1.25\" and 2\" barrel design, this set replaces an entire case of eyepieces for virtually any telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eOne Eyepiece, Five Focal Lengths: The 8-24mm Clickstop Zoom\u003c\/h3\u003e\n\u003cp\u003eThe core of this system is the Hyperion Mark IV, a premium zoom eyepiece designed to rival the optical quality of fixed focal length eyepieces. It provides a continuous zoom from 24mm for wide-field scanning down to 8mm for detailed views of lunar craters and globular clusters. Tactile clickstops at 8, 12, 16, 20, and 24mm allow you to quickly switch between common magnifications without taking your eye from the telescope, making it ideal for tracking targets and adjusting magnification as atmospheric seeing changes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003ePlanetary Powerhouse: The Matched 2.25x Hyperion Barlow\u003c\/h3\u003e\n\u003cp\u003eIncluded in the set, the Hyperion 2.25x Barlow lens was designed specifically to integrate with the Mark IV Zoom. It attaches directly to the 1.25\" nosepiece, converting the 8-24mm focal length range into a high-magnification 3.6-10.7mm range. This transformation turns the eyepiece into a dedicated tool for resolving fine detail on Jupiter's cloud bands, Saturn's rings, and close double stars, delivering sharp, high-contrast views without compromising image quality.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Reverse-Engineered Design: 68° Field at 8mm\u003c\/h3\u003e\n\u003cp\u003eUnlike many zoom eyepieces that have their narrowest apparent field at high power, the Hyperion Mark IV is engineered in reverse. The apparent field of view expands as you increase magnification, starting at 53° at 24mm and growing to an immersive 68° at 8mm. This design ensures that when you zoom in on a target, the view becomes more expansive and engaging, not more restrictive, providing a superior observing experience at the magnifications where it matters most.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Barrel System:\u003c\/strong\u003e The eyepiece is equipped with both 1.25\" and 2\" barrels, allowing you to use it in any standard focuser or diagonal without adapters.\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCamera Ready:\u003c\/strong\u003e The Hyperion Barlow includes a T-2 thread adapter, enabling you to connect a DSLR or dedicated astronomy camera for afocal projection imaging.\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHyperion Zoom vs. Fixed Eyepieces: Optical Convenience\u003c\/h3\u003e\n\u003cp\u003eWhile purists often advocate for fixed focal length eyepieces, a high-quality zoom like the Hyperion Mark IV closes the gap significantly. For mobile observers, outreach events, or anyone looking to minimize gear, the convenience is undeniable. This single set replaces at least five separate eyepieces and a Barlow, reducing weight and eliminating the need to constantly swap accessories in the dark.
