Baader - 8-24mm Hyperion ClickStop Zoom Mark IV Eyepiece

BAADER PLANETARIUM - 8-24mm Hyperion ClickStop Zoom -  Mark IV Eyepiece 

The Baader Hyperion 8-24mm Clickstop Zoom continues the Hyperion tradition of delivering top-of-class performance and quality at reasonable prices.  Telescope zoom eyepieces have earned a less than stellar reputation over the years due to their compromises in optical design and construction.   The Hyperion zoom will surprise many previously disappointed zoom users with its combination of performance, quality, and features.

Some highlights of the Baader Hyperion Clickstop Zoom:

• Consisting of 7 elements, the Hyperion optical design delivers outstanding sharpness and color correction over its wide, flat field even with fast focal ratio telescopes.  Users are reporting that the telescope zoom eyepiece matches the performance of their best fixed focal length eyepieces.
   

• Continuously variable focal length, with click-stops at 8, 12, 16, 20, 24mm. Remains approximately parfocal across zoom range. Click-stops enable precise focal length matching for bino-viewer use.
  
  

• Wide field. The field of view is 68degrees at the 8mm setting, and 50 degrees at 24mm.
  
  

• The Baader Hyperion Clickstop Zoom provides excellent viewing comfort. The eye relief of 12-15mm, large eyelens, and freedom from kidney beaning and blackouts result in a high level of comfort and ease-of-viewing, at all focal lengths.
  
  

• As with the fixed focal length, Baader has gone to great lengths to give this telescope zoom eyepiece the most advanced multicoatings ever used on amateur options. The Hyperion Phantom Group™ multi-coatings truly rival the best in the world - including the famous Zeiss Abbe Orthoscopic! The difference in contrast and transmission is clearly visible at the eyepiece.
   

• Includes both 1.25" and 2" Barrels. The 2" barrel attaches through an included adapter ring that has standard 2"x24tpi SCT threads. The 2" barrel also incorporates a reverse taper groove for better seating and retention.
   

• The Baader Hyperion Clickstop Zoom offers a superb fit and finish. Zoom motion is smooth and precise. Barrels are accurately machined, with excellent surface quality, and hard anodizing. The 1¼" Barrel is threaded for standard 1¼" filters, and the 2" Barrel for standard 2" Filter.
   

• Adjustable rubber eyecup works for both normal and eyeglass users. Rotating eyecup incorporates a variable-height helical adjustment with clickstop positions for setting the optimal spacing.
   

• This telescope zoom eyepiece is designed to integrate perfectly with many popular spotting scopes from Celestron/Synta (M35) and Zeiss (M45). Reaches focus on these spotting scopes even for very shortsighted observers.
   

• Complete System of Accessories for Digital Imaging as a high quality variable magnification optic:
  
  
  • Optically Superb for Digital Imaging
  
  
  • Direct Thread attach to Eyepiece (M43 threads)
  
  
  • Hyperion Digital T-Rings, for direct attachment of virtually every digital camera, camcorder, CCD Camera
    .
