Vixen's HR 1.6 mm Eyepieces are designed for observation of subtle differences of the surface of the planets. The high resolution eyepiece deliver breathtaking, superb images with extremely high level of definition and contrast.

"Their high precision build, over-the-top attention to light suppression and scatter and contrast, comfortable eye relief, very positive focus snap, and uncompromising views make it, in my humble opinion, an optical and engineering work of art." -William A. Paolini Oct 6, 2016

Approx. 100% Strehl ratio on the axis
The resolving power outperforms similar eyepieces designed for planetary viewing. The HR-series maintains
more than a 97% Strehl ratio to the edge of the field of view when combined with a Vixen AX103S refractor.
In comparison, the ratio is about 90% with the use of a standard LV2.5mm eyepiece.

Suitable for Newtonian telescopes with fast primary mirrors
The HR-series work extremely well with the Vixen R200SS as it has the ability to correct coma aberration. Even at the edge of the field of view, the HR-series have a 93% Strehl ratio. In comparison the Strehl ratio with use of the LV2.5mm falls rapidly as the viewing object is moved toward the edge of the field of view. The ratio is only 93% at a
fifth from the center and 0% at the edge. Conventional eyepiece specifications merely show the performance
when an object is put in the center of the field of view of the eyepiece. As a result, the resolving power
declines as you move toward the edge of the field of view. The HR-series are best suited for observing the
surface of the moon to extend your view to the entire field of view.

Simple 5 elements in 3 groups lens design
While most eyepieces are constructed from 7 or 8 lens elements, the Vixen HR-series are constructed with
a 5 lens elements design to achieve the largest possible transmission of light. The absorption and reflection
of light are virtually eliminated.

Enhanced light transmission characteristics
The Vixen AS-coating achieves extremely high light transmission of 99.9% per lens surface. It is applied
to each of the surfaces to deliver extremely high contrast images.

Complete stray light correction
The grooved lens frame construction contributes to the reduction of stray light. The inside of the eyepiece is
perfectly threaded and blackened to prevent deterioration of the image from stray light. The inner baffle rings
effectively stop any stray light. Even a hint of reflection which might occur on the tip of the sleeve is eliminated.
