Baader Hyperion ZOOM 8-24 mm Mark IV eyepiece

Why choose the Hyperion Zoom Mark IV?

Designed to go against the grain of most zooms, theHyperion Zoom Mark IV 8-24 mm focuses on optical quality at maximum magnificationchoice of lenses, careful polishing and design optimized to maintain best sharpness and a field of view that widens as you get closer to the target (up to 68° at maximum zoom). The result is a versatile, precise and pleasing eyepiece that has become a favorite of many astronomers, nature observers and birdwatchers - it's also the only zoom designed from the outset for true binocular use.

5 eyepieces in one: 8 / 12 / 16 / 20 / 24 mm

Visit continuous magnification from 8 to 24 mm is punctuated by ClickStops for 8, 12, 16, 20 and 24 mm focal lengths. These stops make adjustment fast, precise and repeatableeven in the dark. For binocular use, two eyepieces Mark IV synchronize in an instant at the same magnification. The click was softened to avoid disturbing wildlife during close-range observations.

Telescope-side connections

1¼" and 2″ sockets (removable)

The 1¼" and 2″ barrels can be mounted/dismounted according to your angled return or eyepiece holder. One SC 2″ thread enables direct connection on telescopes/mirrors/prisms via optional 2″/2″ ring (ref. #1508080).

Adapters included "A" (spotting scope) & "B" (telescope)

• Adapter A (spotting scope) the Mark IV gains ≈ 4 mm of backfocus and reaches over
  infinity easily on spotting scopes that mechanically accept 1¼" eyepieces but struggle to do MAP.
  Remove the 1¼" turret and use the 1 3/8″ internal thread to screw securely onto
  Celestron Ultima and equivalents.
  Optional bayonet adapter Zeiss Diascope (ref. 2454500) and other SPOT threaded bushes available.
• Adapter B (telescope) Add the space needed to prevent the SC 2″ (5 cm) retaining ring from
  the clamping screws of the angle drive. The SC 2″ ring supplied also secures the fastening on any SC thread,
  including our 2″ diagonal with click lock via 2″/2″ adapter (ref. 1508020).

Refer to the manual for details of adaptor configurations and changes.

Is it binocular-friendly?

Yes. The diameter 55 mmthe ClickStops and theremovable eyecup which frees up nasal space, make the Mark IV particularly comfortable for bino use. Setting two eyepieces to the same magnification is a breeze, even in the dark.

Does it work in cold weather?

Baader revised the zoom mechanism and internal rails for a low-temperature fluid operation.

Can I use it on a spotting scope?

Yes, viaadapter A which adds ~4 mm of backfocus. Solutions exist for Celestron Ultima, Zeiss Diascope (bayonet ref. 2454500) and other models via optional rings.
