IMPORTANT NOTE ABOUT EYEPIECE BRANDING: In late 2017, Docter was purchased by Noblex GmBH of Germany. Noblex continues to manufacture this premium eyepiece at the same facility and to the same standards as before. Noblex branded these eyepieces as 'Docter' through most of 2018. However, starting in Dec 2018, these same eyepieces are now branded and sold as 'Noblex' at a marginally higher price, and not as 'Docter' going forward.

Designed and precision manufactured in Germany, the Noblex (formerly Docter) UWA 12.5 mm is a premium ultra-wide-angle eyepiece that offers spectacular views of the Moon, planets, and deep-sky objects.

The unique optical design of this eyepiece incorporates principles of progressive lens manufacturing as well as high-end glass found in professional optical instrumentation. With an 84-degree apparent field of view (AFOV) and an anastigmatic design, this eyepiece is completely corrected for spherical aberration, coma, and astigmatism. It gives tack-sharp images of stars right to the edge of the field of view. Surface features on the Moon and planets appear razor sharp with neutral color and minimal chromatic aberration.

In his 2013 book Choosing and Using Astronomical Eyepieces author William Paolini wrote of the Noblex/Docter UWA: "This eyepiece maintains an outstanding reputation. Considered by some experienced observers as the best 12.5mm eyepiece made and without peer."

Unlike many ultrawide eyepieces, the Noblex/Docter UWA offers an exceptionally good eye relief of 18 mm which makes it attractive for observers who must wear eyeglasses while observing. It also offers a comfortable viewing experience for all visual observers. With a body diameter of just 55 mm, the eyepiece can be used comfortably in binoviewers over a wide range of interpupillary distances (IPD) for jaw-dropping '3D' views of the Moon, planets, and deep-sky objects.

The Noblex/Docter UWA 12.5 mm eyepiece has concentric 1.25" and 2" barrels that fit both 1.25" and 2" focusers and star diagonals, so you don't need to change diagonal or eyepiece adapter during your observing sessions. A safety undercut is machined into both barrels to engage the focuser thumbscrew to prevent the eyepiece from falling if the thumbscrew is accidentally loosened.

The eyepiece also includes a soft foldable eyecup to comfortably shield your eye from ambient light to ensure maximum image contrast and brightness. This eyecup cam be removed to expose M42x0.75 (standard T or T2 thread) and M48x0.75 male threads for attachment of camera adapters.

Using lead and arsenic free optical glass, the Noblex/Docter UWA eyepiece incorporates 8 lenses arranged in 5 groups. All optical surfaces are anti-reflection coated for high transmission and the brightest possible images. The eyepiece also includes sealing and toroidal rings to ensure it is watertight. The eyepiece accommodates a wide range of filters with standard M28.5x0.6 threads on the 1.25" barrel.

  • 1x 12.5mm ultra wide angle anastigmatic eyepiece
  • 1x plastic eyepiece container and 1 soft storage pouch
  • 1x cleaning cloth
  • 1x product manual / instructions for use
  • Agena end caps
