Baader Hyperion 8-24mm Zoom Mk IV Eyepiece

SKU: BAA2454826 Categories: , ,

The Baader Hyperion 8-24mm Zoom Mk IV Eyepiece is the pinnacle in quality and optics for zoom eyepieces.

Zoom-lenses, in general, are not really famous for high-quality optics. Also, many zoom-eyepieces do not deliver the best possible image quality at high magnification because they were designed with a focus on the price-tag so that image sharpness and field size are getting worse with increased magnification.

The recognition that the Hyperion Zoom Eyepiece enjoys is based on the fact that it was designed the other way around: the glass selection and most of all the principal optical design and consequently the lens polish quality – all were optimized for the highest magnification. And obviously, when closing in on an object you will want the field of view to increase and not to have it become seemingly smaller. Hence the Hyperion-Zoom shows the largest apparent field of view at the highest magnification.

Ideal for:

  • Birdwatching
  • Landviewing
  • Astronomy

What’s new in the model “Universal Zoom Mark IV”?

Even Bestsellers can be improved: The fourth generation of this eyepiece weighs 290 gram and is lighter by 80 grams than its predecessor – it now has 55 mm diameter to become useful in dual mode from 55 mm interpupillary distance, both features make it especially desirable for use with bino-viewers. The adjustable eyecup can be removed to expose the M43 video/photo thread and create the maximum “nose space” for using it on binocular viewers with the supplied winged rubber eyecups – for maximum concentration on the target. The click-stop action has been smoothed out to more easily access the magnification stops at 8/12/16/20 and 24mm (click-stops are mandatory to easily and precisely set both eyepieces to the same focal length for effortless binocular observation without eye-strain). The zooming-mechanism, as well as the inner zooming rails for all lens groups, have been modified to improve cold temperature operation and the parfocalty for each focal length has been finetuned.

Most important, however – the Mark IV offers almost 4 mm more backfocus. This is most beneficial for application with a multitude of spotting scopes. Two different Adapters for telescope and spotting scope adaptation are included with the eyepiece (Spotting-Scope Adapter „A“ and Telescope-Adapter „B“). Read more at “Telescope-sided Connections”).

The Mark IV comes with both the 2″ and 1¼” nosepieces mounted, each nosepiece having its own dust cap and both nosepieces are threaded to accept either 1¼” or 2″ eyepiece filters. Both nosepieces are free of the hated undercuts. Instead, our proprietary Zero-Tilt Safety-Kerfs provide an added measure of security by reducing the tendency of an eyepiece to slip from an unlocked eyepiece clamp. An additional little feature is the Baader-yellow soft pouch with integrated belt strap – which fastens onto many tripod legs just as well, to serve as a bin for all dustcaps that may go astray otherwise.

As usual with Baader eyepieces, the Mark IV offers an M43 photo/video thread on top of the eyepiece, to allow attachment of any desired DSLR or T-2 accessory for mounting a video-camera by means of the optional M43/T-2 adapter ring #2958080. Unchanged is the optical quality, 68° field of view at the highest magnification, Phantom Group multicoatings, a large adjustable eyecup or alternatively two M43 rubber eyecups for bino viewing. An optional spacer ring M43/M43 (#2954250) with 7,5 mm extension enables the user to increase the height of these eyecups in case of need.

The Mark IV likewise accepts adaptation of the 2.25x Hyperion-Barlow onto the 1¼” nosepiece, to transform into a high power zoom, featuring the magnification range of 3.6 to 10.7 mm. The Hyperion Universal Zoom Mark IV is available individually (#2454826) or as a set together with the 2.25x Hyperion Barlow (#2454827)
