The Baader Hyperion Eyepiece 5mm delivers a 68° field of view with 20mm eye relief. Hyperion eyepieces feature Baader's 'Phantom Group' multicoating, sharpening contrast and ensuring excellent light transmission. Each eyepiece has both a 2" and 1.25" barrel and is equipped with both a M43 and SP54 photographic thread, housed under a protective silicone rubber ring. The photographic threads may be used in conjunction with an adapter ring in order to attach to a wide variety of photographic equipment. A variety of focal lengths can be achieved with the use of optional accessories, such as the 2" Finetuning rings (14mm and 28mm) and 2" eyepiece filters. The effective modified focal length when used in conjunction with fine tuning rings and filters is listed under 'further details'. To work out the magnification of your setup, divide the focal length of this eyepiece (5mm) with the focal length of your telescope.

The Baader Hyperion Eyepiece 5mm

  • Wide 68-degree field-of-view with 20mm of eye relief
  • To work out the magnification of your setup, divide the focal length of this eyepiece (5mm) with the focal length of your telescope
  • M43 & SP54 photographic threading rings (for attaching a Baader T-Adaptor or any of a number of other accessories) hidden beneath an ageing resistant silicone rubber eyecup
  • The soft rubber eyecup blocks side-light very effectively in the 'up' position or can be folded flat for eyeglass-wearers
  • Modular design means you can get multiple focal lengths from a single eyepiece by removing the first group of lenses or attaching Baader Fine-Tuning Rings
  • Each fits either a 1.25" or a 2" eyepiece socket without unscrewing anything
  • Baader Phantom-Group coatings - a multi-coating group that maximise light transmission and give ultimate image contrast

The effective focal length of the 5mm eyepiece is as follows:

  • With 14mm fine tuning ring: 4mm
  • With 28mm fine tuning ring: 3.2mm
  • With both fine tuning rings: 2.6mm
  • With 2" Baader filter: 4.3mm
  • Removing first group of lenses: 22.5mm
