KOWA 25-60x Zoom TE-11WZ wide field eyepiece


 

Last March 2013, KOWA released its latest LARGE FIELD Zoom eyepiece for the TSN-880 and TSN-770 series telescopes.

It is the already popular PROMINAR TE-11WZ Wide Field Zoom Eyepiece.


Technical Features:

  • TE-11WZ optical design contains 2 XD lenses. The first KOWA eyepiece to be PROMINAR coated.
  • Compared to the 20-60x Zoom eyepiece(TE-10Z) offered for this series, the new TE-11WZ offers a 20% larger field of view.
  • The images they deliver are surprisingly sharp even when working at 60x.
  • Chromatic aberration is limited to the highest level. We could speak of virtual elimination of chromaticity.
  • Its 17mm eye relief remains identical whatever the magnification at which you are working.

Technical specifications:

  • Magnification range: 25-60x wide field
  • Actual field of view: 2.4° - 1.32°
  • Exit Pupil: 3.5 - 1.5mm (TSN-880) / 3.1 - 1.3mm (TSN-770)
  • Relative Brightness: 12.3 - 2.3 (TSN-880) / 9.6 - 1.7 (TSN-770)
  • Eyepiece Relief: 17mm
  • Field of View at 1000m: 42 - 23m
