do you have an adapter that will attach Mark 4 zoom to a Sony FDR AX53 movie camera? It provides a 55mm filter thread to attach to the camera.

Hyperion Zoom 2 Zoll und 1.25 Zoll

The Hyperion ClickStop Zoom Eyepiece with 1¼" and 2" Connector

There is an old saying that there is nothing like an eyepiece with fixed Focal length, if it should be the highest image quality. But this zoom eyepiece is second to none fixed focal length eyepieces, saving especially during mobile use so you don't have to carry many eyepieces around.

The Hyperion Universal Zoom is a perfect solution for all hunter, birdwatchers and astronomers alike, it brings a whole range with focal lengths from 8 to 24mm in a single high-quality eyepiece! It lets you continuously zoom with Clickstops at 8, 12, 16, 20 and 24mm. The only difference to the fixed focal length is that the field also varies from 53 Degrees at 24mm focal length up to 68 degrees at 8mm. This eyepiece was "Reverse" constructed unlike most other zoom eyepieces: largest field of view and the sharpest image at the highest magnification.

See a more detailed description of the eyepiece and its possibilities at the individual product page

Caution: On spotting scopes you can use the Hyperion zoom eyepiece only without the Barlow lens!

Hyperion zoom Barlow lens - 2.25x

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

Some highlights of the Hyperion Zoom Barlow Lens

  • Triplet lens design for highest optical quality
  • Anastigmatic Flatfield Design for high sharpness all over the field of view
  • Baader Phantom CoatingTM Group for highest contrast and light transmission

Connections Eyepiece side

  • Direct connection to any Hyperion Zoom with Barlow-adapter A
  • T-2 (M42x0.75 mm) thread with Barlow-adapter B
  • 1¼" filter thread without additional Adapter

Attention: The Barlow lens is only suitable for use in astronomical telescopes; the use of spotting scopes is not possible.
