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.

Is there a lunar filter that you recommend for use with this model, both with and without the Barlow attached? I'm assuming 1.25" but I've not been able to confirm elsewhere. Thanks!

I can't manage to focus my Hyperion Universal Zoom Mark IV when it is on 8mm setting. I am using Celestron Astro fi 6", with 1 1/4 Celestron visual back replaced with Baader 2" ClickLock SC clamp, and a 2" BBHS Prism Diagonal. On all other settings I can focus with no problem. Also will I damage the prism if I use the Barlow that comes in this set?

Hello, I already have one of first version of the Hyperion zoom (there's only written Hyperion 8-24mm Clickstop-Zoom (Phantom Group Coated)) and I want to ask you: can I use it in pair with a Mark IV or III with a binoviewer..? Or should I avoid because of different size of the barrel...or different size of exit pupils ? Thank you very much for your answer and attention. Saluti

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.

Great product!
I've enjoyed using the Baader Universal zoom a lot. It's sturdy, solid and you can feel quality craftsmanship. It's easy to use outdoors and the views are excellent. I'm happy as I feel that I got what I paid for. The Barlow has been great well. The only minus I can give about it that the markings themselves won't probably last a lifetime and are starting to wear out slightly already. Other than that, it's all good and I'm already purchasing another one of these zooms for my upcoming Maxbright binoviewer set.
  • Quality, ease of use, reliability
  • The markings are starting to wear out a little bit

Hyperion 8-24 Universal Zoom Mark IV mit Barlow 2,25x
Sehr gute Verarbeitung. Vielseitige Nutzbarkeit durch verschiedene Anschlussgewinde, Steckhülsen 1,25 und 2 Zoll, Augenmuscheladapter. Gut geeignet für Brillenträger. Exakte Rastung der Zoom Einstellungen. Ich nutze es zur Zeit an einem APO 80 mit Amici Prisma zur Naturbeobachtung. Einfach toll ohne Okularwechsel zu beobachten. Sehr kontrastreiche und scharfe Bilder.
Ich habe das Okular mit der optional angebotenen Barlow 2.25x erworben. Sehr gut aufeinander abgestimmt. Gewinde passen alle sehr gut zusammen. Astronomisch habe ich diese Kombination noch nicht genutzt.
  • Sehr wertige Verarbeitung, Sehr scharfe und kontrastreiche Bilder über alle Zoom Stufen.

Ja, ich habe mich lange gesträubt davor ein Zoom Okular zu kaufen. Zu viel Respekt vor dem berüchtigten Tunnelblick und den zahlreichen "Festbrennweiten sind besser" Aussagen.

Manchmal möchte man aber den Okularwechsel vermeiden, wenn man gerade das Objekt gefunden hat oder gerade den richtigen Filter eingeschraubt hat. Und so dann doch der Entschluss, das Baader Hyperion Zoom soll es sein in Kombination mit dem Barlow Adapter.

Ja, das Produkt hat seinen Preis, aber habe ich den Kauf bereut? Ganz und gar nicht! Die Qualität, sowohl vom Aufbau als auch vom Bild, ist äußerst überzeugend. Schärfe und Abbildung, da passt alles.
Es ist äußerst flexibel einsetzbar, sowohl für Deep Sky als auch Planetenbeobachtung. Ich erreiche damit ein Feld von etwa 2,3° bei 24mm, was dieses Okular auch für großflächige Objekte sehr gut nutzbar macht. Für Planeten dann mit der Barlow und dann geht's los.

Schmeiße ich jetzt meine Festbrennweiten weg? Das sicherlich nicht, auf mein 2" Übersichtsokular mit 70° oder mein 13,4mm Galaxienjäger werde ich sicherlich nicht verzichten. Aber das ist sicherlich auch nicht die Aufgabe des Zoom Okulars.
Aber ganz ehrlich, man hat gar nicht den Eindruck, dass es ein Zoom Okular ist. Vielmehr hat man den Eindruck es sind einfach 5 sehr gute Okulare in einem Gehäuse. Hier kann man ganz klar eine Empfehlung aussprechen. Wer dieses Okular kauft, hat eigentlich ausgesorgt. Vielleicht noch ein Übersichtsokular und ein spezialisiertes Okular für den Anwendungsbereich und fertig
  • Breites Anwendungsspektrum
  • Bis jetzt nichts
