The 13 mm Hyperion says I can use fine tuning rings. What is the difference between a 13 mm Hyperion with a tuning ring or just purchasing an 8 mm Hyperion eyepiece? Do I lose clarity or brightness or? Thanks for your reply!

Is there a way to determine which lower barrel (1.25" nosepiece) belongs to a particular Hyperion? I have 13mm and 21mm Hyperions. The 21 behaves like a shorter eyepiece, and the 13 seems to have low eye relief. These were not new, so there may have been a mismatch along the way.

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.

Hyperion 13 mm am bino
Hallo
Mein eindruck an meinem 12 zoll newton von den 13 mm hyperion.

Im bino für mich eine tolle abbildung.
Der einblick tadellos und auch meine nase passt dazwischen (65 mm augenabstand) tolle gummi ummantelung liegt sehr angenehm an der nase und die okulare sind für mich sogar selbst im bino mit brille voll nutzbar! Tolle ausstattung beim okular da viel zubehör dabei ist.
Die augenmuschel individuell einstellbar oder tauschbar.absolut genial für mono oder bino betrieb.
Schärfe und kontrast find ich sehr gut von der gezeigten abbildung!

Jupiter zb zeigt mir mit dem baader planetenfilter schwache details die ich mit anderen okularen bislang so noch nicht gesehen hatte. Kugelsternhaufen galaxien und co einfach toll.
Sternabbildung punktförmig.

Mich überzeugen die 13mm hyperion auf ganzer linie im bino betrieb!
Für mich ein gutes okular was viel freude beim beobachten macht
Sowie eine gut performende okularserie die tolle beobachtungen ermöglicht.


  • Gute optische leistung,im bino sehr komfortabel
  • Geringfügig aufgehellter randbereich

Great mid power, most used focal length
A very comfortable to use eyepiece in the 13 mm focal length.
68 degree is quite wide for most users. This eyepiece represents outstanding quality
at a reasonable price. A lovely Baader feature is that the Hyperions will fit
both 1.25" and 2" focusers/diagonals. Nice fit and finish with an easy to identify colour
band (not that that helps much in the dark). I use this unit mainly for Hydrogen-Alpha solar observations where it performs better than some wider field eyepieces with more elements. ( I used the 21, 13 & 8mm Hyperions)
I also think the Baader multi-coatings make a difference.
Overall highly recommended for those seeking to balance quality vs price.
