Observe the Moon and planetary surface with Vixen's overwhelming sharp and high contrast HR eyepieces.

The high resolution HR eyepieces are designed for observation of subtle difference of surface of the planets, detailed surface features of the Moon and challeging double stars. The HR eyepieces create breathtaking, superb images with extremely high levels of definition and contrast.

High resolution, high contrast and "super" high magnification eyepiece

• High resolution and high contrast are required for observation of subtle difference of surface of the planets. HR eyepieces are super high magnification and designed for good performance in short focal length letescopes. With long eye relief, it is not stressful to look through despite high magnification.

High resolution

• Strehl raio approximately 100.0%
  As a result of thorough pursuit of high resolution, when combined with the F8 no-abberation telescopes, the Strehl ratio of 100.0% was achieved at the center of the field of view. It is 97% or more even near the edge of the field of view.

• Suitable for Newtonian telescopes with fast primary mirrors
  The HR eyepieces work extremely well as it has the ability to correct coma aberration. 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 and and it fell to less than 40% near the edge. However, using HR eyepieces, the strehl ratio of 93% or more was realized even near the edge of the field of view and you can observe the surface of the planets or the moon throughout the field of view.

High contrast

• Simple 5 elements in 3 groups lens design
  While most eyepieces are constructed from 7 or 8 lens elements, the Vixen HR eyepieces 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.

• 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.

High magnification

• Generally, it is said that the limit of useful magnification for a telescope is two times the effective aperture in millimeters. (Example: For a 100mm refrector, the maximum useful magnification is 200x) However, if you select the good equipments and observation conditions, this is not the limit. If you have high-quality equipment and skill of handling high magnification, it is possible to observe even at ultrahigh magnification that you have never experienced before.
