The HR 2.4mm Eyepiece from Vixen Optics is designed for observation of subtle differences on the surface of the planets. It maintains more than a 97% Strehl ratio to the edge of the field of view when combined with a Vixen AX103S refractor (sold separately).
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.
Suitable for Newtonian Telescopes with Fast Primary Mirrors
The eyepiece works well with the Vixen R200SS as it has the ability to correct coma aberration. Even at the edge of the field of view, it has a 93% Strehl ratio. The eyepiece is suitable 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
The eyepiece is constructed with 5 lens elements to achieve maximum transmission of light. The absorption and reflection of light are virtually eliminated. It is made in Japan.
Enhanced Light Transmission Characteristics
The Vixen AS-coating achieves high light transmission of 99.9% per lens surface. It is applied to each of the surfaces to deliver high contrast images.
