If you don't yet have a Baader Hyperion Zoom eyepiece, but want to use a superior APO quality Barlow lens with your 1.25" eyepieces, here is the perfect combo that contains the Baader Hyperion Zoom Barlow and the 1.25" Click-Lock Eyepiece Clamp
Big saving when you buy them in this combo!

The Baader Hyperion Zoom Barlow 2.25x, specially designed for the Baader Hyperion Clickstop Zoom Eyepiece Mark III with triplet lens design for non-astigmatic flat field suitable to complement the high image quality of the Hyperion Zoom Eyepiece. Converts the Baader Hyperion Zoom Eyepiece into a 3.5 - 10.5mm high power astro-zoom eyepiece with excellent image quality for high resolution solar, lunar, planetary and double star observations.

Together with the T-2 adapter (included) the Hyperion Zoom Barlow can likewise serve for any other projection application from 1.3 up to 6x magnification factor. The image quality truly is astonishing. We found no difference to the original Carl Zeiss Jena Barlow units.

As with all Baader in-house development, we try to make our products usable for the widest range of applications - just as we've done it with the Hyperion Zoom Barlow. Below we describe these applications in further detail... 

You can simply and easily screw the Hyperion Zoom Barlow into any Hyperion 8-24 mm Zoom Eyepiece. The sharpness on axis as well as off axis are well maintained, with your choice between 1.25" or 2" mounting.

Further applications of the Baader Hyperion Zoom Barlow
Visual use (all preview images can be enlarged by clicking):

Combined with an Click-Lock T2 to 1.25 "or 2" adapter we can create a classical Hyperion APO Barlow lens that is suitable for all eyepieces (in this above example shown with a Zeiss Abbe eyepiece). Please note, some eyepieces might show slight vignetting, depending on their design.

Above, the example on the left shows a 1.25" ClickLock Eyepiece Clamp 2458100, (but it could also be the alternative 1.25" Focusing Eyepiece Holder 245 8125) between the Barlow and the eyepiece. In the second example, you could set either the Baader 1.25" Maxbright Mirror Diagonal or the Baader T2 90-deg Prism Diagonal between them.

Photographic applications (click on the image to enlarge):






Through the included T2 adapter, the Hyperion Barlow is adaptable to any DSLR or CCD camera. The optical performance is equivalent to that of an excellent converter lens. The sharpness over the whole field is maintained especially well.




With the help of the Hyperion T-adapter and the Hyperion DT-Rings, the Hyperion Barlow can be adapted for afocal eyepiece projection to (almost) all compact DSLR cameras and camcorders.
