7x Baader 1.25" Hyperion Eyepieces - completely with travel case

A packet offer for a special price: 7pc Baader 1.25" Hyperion eyepieces in a useful case with cut foam inlays. Now you are ready for nearly any astronomical task! The standard set contains the following focal lengths: 5, 8, 10, 13, 17, 21, 24 mm including the case. Alternatively, you may also choose other focal lenghth (also the new 10 mm) and/or more eyepieces of one focal length. The only limitation is the number of eyepieces (seven).
If you want to choose an individual set of focal lenghts, you can do so during the order process. On the page you choose the payment method you can find a text field. Please write down the focal lenghs into this field. You also can order 2 or more Hyperion with the same focal lengh.

Excellent Image Quality up to the Periphery

Baader Hyperion eyepieces were designed for excellent image quality throughout the large field of view. Even with fast Newtonian telescopes the image will remain crisp up to the periphery. The Hyperions are also a lot cheaper than several comparable eyepieces, making them the ideal choice for discerning users who not only wish to get good quality, but also look for an excellent value for money.

Digiscoping / Photography

In addition to their superb visual performance the Hyperions are also ideally suited for photography. Their integrated threads are the basis for a rigid adaptation of your DSLR camera or compact digital camera.

1.25" and 2" Telescope Adaptation

Optically the Hyperions are 1.25" eyepieces. For a more solid grip you may choose to attach them to a 2" focuser. The eyepiece body has an integrated 2" barrel with safety undercut in addition to the 1.25" barrel. Using this barrel will move the eyepiece a few centimetres closer to the telescope, which might be important when on use in a telescope with a tight back focus distance. Warning: Do not use this feature in a 2" star diagonal or prism diagonal! The 1.25" barrel might collide with the mirror!

Specifications and Features for Visual Use

68° Apparent Field of View: With their large 68° FOV the Hyperions are true wide angle eyepieces. They offer a crisp image up to the periphery and a long eye relief for comfortable viewing.

Superb Image Sharpness: The intricate optical layout of the Hyperion eyepieces results in an excellent image sharpness both on the optical axis and up to the periphery of the large field of view. Even in very fast Newtonians down to f/4 there will be only a very moderate degradation in sharpness towards the edge. This is particularly important for Dobsonian telescopes where a larger useful field of view effectively means that higher magnifications can be used successfully!

High Transmission and Contrast: Hyperion eyepieces feature an excellent multicoating on all glass-to-air surfaces. The lens edges are carefully blackened. As a result you get a bright, clear and crisp image without distracting reflections or ghost images.

No Kidney Beaning: Many wide angle eyepieces suffer from an effect called kidney-beaning. This refers to an annoying black shadow entering the field of view when you move your eye a little out of the optical axis of the eyepiece. The result of this kidney-beaning is that viewing through the eyepiece is much less comfortable. Baader Hyperion eyepieces have oversized lenses in order to avoid this effect and reduce it to a minimum.

No Vignetting: The large lenses offer a constantly illuminated field of view. In many simpler eyepieces you will notice a degradation of the image brightness towards the edge of the field of view.

Suitable for Binocular Use: Hyperion eyepieces have a large eye relief and a comfortable and "forgiving" viewing position. This makes them ideal for use on a binoviewer. The eyepieces are comparatively large, but most users will not have a problem. The minimum interpupillary distance (=distance between your two eyes) is 56 mm. Due to their ergonomic shape the nose finds a comfortable position between the eyepieces.

1.25" and 2" Telescope Adaptation: Optically the Hyperions are 1.25" eyepieces. For a more solid grip you may choose to attach them to a 2" focuser. The eyepiece body has an integrated 2" barrel with safety undercut in addition to the 1.25" barrel. Using this barrel will move the eyepiece a few centimetres closer to the telescope, which might be important when on use in a telescope with a tight back focus distance. Warning: Do not use this feature in a 2" star diagonal or prism diagonal! The 1.25" barrel might collide with the mirror!

Specifications and Features for Photography

Easy Adaptation of Cameras: The 1.25" Hyperion eyepieces have an M42x0.75 thread as well as a recessed M54x0.75 thread. These threads can be used for the adaptation of various cameras.
We offer a broad range of adaptors and stepping rings to the most common thread sizes.

Suitable for heavy cameras: Several powerful cameras are rather large and heavy. The adaptation to most standard eyepieces is a little risky. The threads of the Hyperion eyepieces are integrated parts of the eyepiece´s body. This allows you to attach heavy eyepieces securely.
