I am looking at the Hyperion range eyepieces. Will these be compatible for the Orion 10" f/3.9 Newtonian Astrograph Reflector Telescope?

Where can I get replacement dust caps for Hyperion 24mm and 13mm

Rating of Question

I'm curious what wavelength range the Hyperion line of eyepieces is corrected over as well as the metric for image quality. Since these are taking the image from the telescope and re collimating it to be imaged by either a camera or the eye, I'm curious what practical resolution can be achieved assuming the systems on either side are 'perfect'. Put another way, what would be the spot size at the focal plane if collimated light were sent in to the eyepiece backwards?

I’m looking at the Hyperion 24mm and Hyperion 8mm eyepieces. I’m hoping to maximize the capability of my new Celestron NexStar 127mm (FL=1500mm, f/12). Are these eyepieces compatible?

Baader Hyperion 68° Modular Eyepiece

Make the most from your telescope!

Most telescopes are supplied with one or two simple eyepieces in the set, which do not exploit the performance of the optics. Moderate contrast and sharpness and small field of vision quickly spoil the fun of the sky observation. With Hyperion eyepieces you get everything out of your telescope!

They are suitable for photo! Keep your Astro eyepiece impressions forever by connecting the cameras and camcorders at the Hyperion!

You can distinguish between the series with "Prime lenses" f = 5 mm, 8 mm, 10 mm, 13 mm, 17 mm, 21 mm, 24 mm, the two great eyepieces aspheric 31 mm and 36 mm, as well as the Hyperion zoom eyepiece with infinitely variable focal length of 8 mm to 24 mm.

The 68° "Fixed Focal Length" - series of the Hyperion eyepieces

Hyperion zoom on the Celestron spotting scope
The word fixed focal length is here in this brief description in quotes because you are treated as a user by the modular structure of the eyepieces in the position to change the focal length. The fixed focal length Hyperion eyepieces are Multi function eyepieces .

A variety of ways

Connection of cameras and camcorders

The Hyperion eyepieces have above ("eye-side") two system thread. To expose them, either the eyecup or the large thread protection ring must be removed. For one, it's an M43 thread and continue to a second with SP54 thread; the M43 thread (system thread 1) accessories, E.g. for the normal eyepiece projection is used for connection of T2. A M34 on T2 transition ring (Hyperion M43/T-2) is to switch threads between them (known as afocal projection), the thread SP 54 (system thread 2) is used for connecting digital cameras or camcorders, where the lens can not be removed.

Focal length variability and filter insert

A variety of additional Hyperion focal lengths can be obtained by using our 2" fine tuning extensions rings 14mm and 28mm, or even with our 2" eyepiece filter set. Thus an eyepiece of 5mm focal length can be converted into one of 2.6mm focal length - without loss of sharpness - above all, because no additional lenses are introduced into the bean, which is unavoidable when using a Barlow lens. Also you can of course astronomical 1¼" eyepiece filters in the 1¼" screwing the eyepiece barrel.

Accessory case included with the Hyperion beginner set and complete set. Also available separately.

Further focal modification there are tweaking our rings (FTR) with 14 - and 28mm length. The different possible focal lengths when removing the first lens group, and in combination with filters and fine tuning rings can be found in the table above.

Stop ring (#2958097): Another "clever" accessories for our Hyperion eyepieces is the stop ring. It can be used, the insertion of the eyepieces set so that each eyepiece gives a sharp image instantly when plugged into a 2" diagonal mirror.

Hyperion eyepieces 6-page user manual

Due to the wealth of functions, there is the Baader Hyperion eyepieces own, 6-page instruction manual to explain the variety of connection options of cameras and all the possibilities of the focal length fine tuning.

Hyperion fixed focal length eyepieces on the Zeiss Diascope spotting scope

The Hyperion fixed focal length eyepieces are also at Zeiss Diascope spotting scopes can be used. You will need the Baader Diascope eyepiece bayonet 1¼ "Adapter (#2454500) for the connection of 1¼" Astro eyepieces on the Zeiss Diascope spotting scopes. He is using the 1¼" socket of the Hyperion eyepiece pushed and fixed by means of 3 small screws on the socket. The Diascope spotting scope is the Zeiss bayonet ready available, so that the complete unit Hyperion Zeiss spotting scope used eyepiece and Baader bayonet adapter directly into the Zeiss spotting scope.

Baader Phantom Coating® Group

Baader Phantom Group Coating is a 7-layer broadband coating with extremely low residual reflection. The term "Group" indicates that for each type of glass of the lenses, which come into the Hyperion eyepieces to apply, each effective anti-reflection layer system was expected.

All these various anti-reflection coatings on each glass surface were then optimized so that they are most effective where the human eye has its highest sensitivity at night - at about 520 nm - in the green region of the spectrum.

The best anti-reflection appears almost colourless: this proves that the anti-reflective coating over the entire visible spectrum is equally good effect. Phantom Group anti-reflection coatings are - depending on the type of glass - almost entirely colourless. In this way it is ensured that the least amount of light for a night-adapted eye is lost without any stray light.

If a multi-coated lens (eyepiece or lens) with direct view from the front shows a strong green reflex, then it is not phantom group to a Baader anti-reflective coating! The intensive green reflex is a sign of a little sophisticated coating technique and means that in the spectral range between 500-550 nm the most light is reflected, i.e. is lost.

24 mm hyperion okular
Guten abend
Ich hatte vor kurzem über das 24 mm hyperion okular mit ihnen geschrieben da ich div. probleme beim beobachten hatte und sogar dachte das das okular leider qualitativ nicht zufriedenstellend ist .genutzt visuell an meinem 12 zoll newton.
Ich muss meine aussage korrigieren da der fehler bei mir als brillenträger mein astigmatismus im auge ist und sie mir außerordentlich gut dabei geholfen haben dieses zu erkennen und zu verstehen dank ihrer hervorragenden fachlichen hilfe und kompetenz!!! Das 24 mm hyperion ist abbildungstechnisch für mich ein top okular! Vorher ohne brille hatte ich immer gezogene sterne und keine scharfe hatte das keinen spaß gemacht. Ich habe es jetzt nochmal ausgiebig mit brille getesten und was soll ich sagen.ich bin begeistert!Punktförmige sterne bis kurz vor den rand des GF und eine sehr scharfe kontrastreiche abbildung.jupiter zb trotz kleiner vergrößerung ist knackscharf und strukturiert.sternhaufen sind unglaublich schön anzusehen. Ich bin mehr als zufrieden nach meiner leidigen problematik und suche ein so tolles okular zu besitzen und vorallem sehr dankbar für ihren service!!! Nicht selbstverständlich!
Ich werde bei ihren produkten bleiben!

Vielen dank

Ein Okular der Sonderklasse
Sehr gutes und hervorragend verarbeitetes Okular mit 68° scheinbarem Gesichtsfeld. Der große Augenabstand ist auch für Brillenträger wie mich sehr komfortabel. Dieses Okular ist nicht "billig" , aber für diese Qualität ein wirkliches Schnäppchen!
  • Die Schärfe bis an den Rand!
  • Nichts!

Muscheln der Hyperions
Die Hyperions sind zweifellos gute Weitwinkel-Okulare, nur zu schade, dass sie noch diese höchst unpraktische, antiquierte, stülpbare Gummi-Augenmuscheln haben, wo heute drehbare Muscheln praktisch standard sind, auch bei billigen Okularen ab 40-50€. Es gibt immer mehr Brillenträger unger den Astronomen, und für sie sind drehbare Muscheln unheimlich praktisch, weil sie nicht nur zwei, sondern unendlich viele Positionen erlauben.
  • Gute optische Qualität , habe das 13mm

Baader Hyperion
These eyepieces are outstanding and well worth the money. Buying these are a massive jump from the cheaper standard stuff they really give you the views and contrast you want to see. Where i live in the Uk its very cold so for me they needed to be able to withstand a certain coldness and not just freeze up in the first 10 minutes and they have not failed me. I bought my first one, This one in fact at a star camp which was hitting minus 5, And could not of asked for anything better.

  • Build quality is outstanding
