Baader Hyperion Universal Zoom Mark IV Eyepiece & Barlow

Further details

For many birders, observers of nature and astronomers alike, the Hyperion Zoom Eyepiece is their favourite eyepiece, it is also the only zoom-eyepiece that was designed from ground up to be used with bino-viewers.

Either 1¼" or 2" can be used with the Hyperion Universal Zoom Mark IV

Includes all features of the popular Hyperion Zoom Mark III, as well as
Low weight (290g/10,2oz), slim design of 55mm diameter (perfect for binoviewing)

Zero-Tilt safety kerfs instead of the inconsistent undercuts in the barrels

Includes 2" SC-thread for the shortest possible adaptation to telescopes or prisms/mirrors

4mm backfocus increase with spotting scope A-Ring (included): the Mark IV focuses with all tested spotting scopes (optional adapters available for most major brands)

Clamping screw distance improved with telescope adapter B-Ring (included)

Eyepiece holster included with belt strap which hold also firmly on tripod legs

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 it´s 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 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 set together with the 2.25x Hyperion Barlow (#2454827)

Telescpope-sided connections

Spotting Scope-Adapter A: 4mm gain on backfocus. the Mark IV focuses with all tested spotting scopes (optional adapters available for most major brands)
Many spotting scopes nowadays do allow the mechanical insertion of astronomical 1¼" eyepieces – but in many cases this combo cannot focus to infinity. By utilizing the supplied spotting-scope adapter ring "A", the Hyperion Universal Zoom reaches almost four mm deeper into the eyepiece clamp of all those spotters, to safely reach infinity focus. When removing the 1¼" nosepiece, a 1 3/8" thread inside the "A"-ring will make the Mark IV firmly thread onto all Celestron-Ultima spotters and it´s namesakes. Optional available is a bayonet-adapter for Zeiss Diascope-spotters (#2454500). Threaded adapters for many other famous spotting scope brands (that still don´t allow 1¼" eyepiece adaptation) will become available in the future – now that it makes sense to produce them

Telescope-Adapter B: Sufficient distance to clamping screws..
When using the Mark IV on a telescope though, the "B"-ring (supplied) should be chosen instead, to keep the bottom of the eyepiece flush with the upper end of most star diagonals. Otherwise the bottom 2" SC-threaded holding ring that holds the "A" or "B" ring in place may directly rest on the clamping screws of the star diagonal. The supplied 2" SC-ring also allows the Mark IV to firmly mount the eyepiece onto any SC-thread,

Camera-sided Connections

As usual with Baader eyepieces, the Mark IV offers an M43 photo/video thread on top of the eyepiece to directly attach most video cameras. It also allows attachment of any desired DSLR or T-2 accessory by means of the optional M43/T-2 adapter ring #2958080. An optional spacer ring M43/M43 (#2954250) with 7,5 mm extension enables the user to increase the height of the included eyecups in case of need or to attach M43 cameras without touching the lenses.

Three different eye cups are included in the basic equipment of the eyepiece.
Initially mounted is the large height-adjustable eyecup that also fastens onto the M43 photo-thread of the eyepiece. By rotating it counterclockwise the height will increase. This eyecup easily unthreads simply by rotating it upward further than the uppermost stop - this reveals the M43-thread connection
A none-folding rubber eyecup alternatively fits straight onto the M43-thread. This is the preferred solution for observers without glasses at a binoviewer. It gives you enough room for your nose and good support to keep the perfect eye distance.
An even lower eyecup with foldable winged eye shield especially serves for wearers of eye glasses, the flappable side shields block stray light and side image information not part of the eyepiece field of view. This helps to concentrate on the target when using a binoviewer.

The 2.25x Baader Hyperion Zoom Barlow lens was designed especially to complement the Hyperion Zoom eyepiece. It converts the regular focal lengths of 8 to 24 mm to a range of focal lengths between 3,6 and 10,7 mm, while retaining the outstanding image quality for observing sun, moon, planets and double stars with high resolution.

The Mark IV Zoom, in conjunction with or without the Hyperion Barlow, covers all focal lengths between 3.6 to 24 mm.

The Hyperion Barlow works with every Hyperion 8-24 mm Zoom eyepiece ever produced. The barlow is attached onto the 1¼"-nosepiece. Because of the dual nosepiece of the Mark IV, it can be used at telescopes with 1¼" or 2" eyepiece clamps.

The Hyperion Barlow comes with a T-2 thread-adapter, to mount the Barlow in front of any camera or other accessories with T-2-threads. Combine it e.g. with a DSLR-camera – in this way the camera body will be equipped with a 1 ¼" nosepiece. The camera body just needs a standard T-ring to fit it onto any 1 ¼” eyepiece holder.

Attach the lens unit without the Barlow-adapter (A) directly onto many 1¼" eyepieces, whenever they do not already have an integrated barlow element. The result is a 2x Barlow with very good optical properties (see left image).

Hyperion Barlow and DSLR
Also included is an adapter on T2-thread. Thus, the Barlow can be used - for example, on a DSLR with T-Ring

    Excellent service from Harrison Telescopes  (24/10/2022) -

  Great for a beginer  Just inherited my first telescope and only came wit one eyepiece so being new to the hobby i wanted something to make my time easier at the telescope. I have only had maybe 2 clear nights but the firs night i managed the moon and was blown away by the views. Second time out it was Jupiter Awesome!!!  (05/09/2021) Paul - Durham

  Great service from Harrison's & great eyepiece  Firstly, the eyepiece and Barlow arrived promptly and in perfect condition, which is as much as you can ask for when ordering online, so top marks to Harrison's. Secondly the eyepiece & barlow I used on my firstventure into the night sky. No planets out but the moon looked incredibly sharp/detailed  (31/01/2021) Pete - Lincoln

  A fine upgrade for supplied oculars  Upgrade for the eyepieces of my Sky-Watcher 200P Dobsonian following glowing reviews on the forums. It made sense to get the Barlow bundle as well. This hits the sweet spot in terms of optic quality, range of magnification, convenience and cost. A quality product and image quality superb.  (16/01/2021) B Laniosh - Worcestershire

  Hyperion Mk4 Zoom & Barlow  Great service and prompt delivery. Recommended.  (01/08/2020) G Robertson - N Wales

  Fine piece of kit  New to Astronomy I have a celestron Nexstar 4SE the optics of which are a fine starter. The supplied eyepiece is rubbish, particularly if like me you wear glasses. The convenience and build quality of the zoom eyepiece is a real improvement and avoids fumbling for kit in the dark.   (16/05/2017) - Swindon
