  • Baader Hyperion Universal Zoom Mark IV w/ 2.25x Barlow

    This 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.

    One Eyepiece, Five Focal Lengths: The 8-24mm Clickstop Zoom

    The 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.

    Planetary Powerhouse: The Matched 2.25x Hyperion Barlow

    Included 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.

    A Reverse-Engineered Design: 68° Field at 8mm

    Unlike 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.

    • Dual Barrel System: The eyepiece is equipped with both 1.25" and 2" barrels, allowing you to use it in any standard focuser or diagonal without adapters.
    • Camera Ready: The Hyperion Barlow includes a T-2 thread adapter, enabling you to connect a DSLR or dedicated astronomy camera for afocal projection imaging.

    Hyperion Zoom vs. Fixed Eyepieces: Optical Convenience

    While 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. It offers the ability to precisely frame any object by dialing in the exact magnification needed, a capability a fixed eyepiece set cannot provide.

  • How does the Baader Hyperion Zoom Mark IV achieve its full 3.6-24mm range?

    The set includes two components. The Hyperion Mark IV eyepiece provides the base 8-24mm zoom range. The included 2.25x Barlow lens attaches to the eyepiece's 1.25" nosepiece, multiplying the magnification and shifting the range to 3.6-10.7mm. Together, they cover the entire spectrum from 3.6mm to 24mm.

    What is the apparent field of view of the Hyperion Zoom IV at different focal lengths?

    The apparent field of view (AFOV) changes as you zoom. It is approximately 53° at the 24mm setting and increases as you zoom to higher power, reaching a maximum of 68° at the 8mm setting. This design provides a wide, immersive view at high magnifications.

    Is the Hyperion Zoom Mark IV suitable for planetary viewing on a Celestron 8" f/10 SCT?

    Absolutely. On a typical 2032mm focal length 8" SCT, the Hyperion Zoom with the 2.25x Barlow provides a magnification range from 189x (at 10.7mm) to an extremely high 564x (at 3.6mm). This gives you ample power to observe Jupiter's Great Red Spot and the Cassini Division in Saturn's rings, allowing you to adjust magnification instantly to match atmospheric seeing conditions.

    Can I use the Hyperion 2.25x Barlow with my other 1.25" eyepieces?

    While the Barlow was optically matched for the Hyperion Zoom, its lens unit can often be threaded directly onto other 1.25" eyepieces that have standard filter threads. However, its performance and magnification factor may vary with eyepieces of different optical designs.

    How would the Hyperion Zoom perform on the Orion Nebula (M42) in a 10" f/4.7 Dobsonian?

    In a 1200mm focal length Dobsonian, the Hyperion Zoom is extremely versatile. At 24mm (50x magnification), you can frame the entire Orion Nebula and its surrounding nebulosity. You can then zoom into 8mm (150x magnification) to resolve the four main stars of the Trapezium (Theta Orionis) at the nebula's core, all without changing eyepieces.

    Can I connect a camera to the Baader Hyperion Zoom Mark IV?

    Yes. The included 2.25x Barlow features a T-2 thread adapter. By using a standard T-Ring for your camera model (DSLR or mirrorless), you can securely attach your camera body to the eyepiece assembly for high-magnification afocal photography of the Moon and planets.
