SLV eyepieces offer maximum observing comfort thanks to their 20mm eye relief even at the shortest eyepiece focal lengths. Residual chromatic aberration is reduced to an absolute minimum by employing high quality lanthanum glasses. All air-glass surfaces are provided with a sophisticated multi -layer hard coating which reduces by irritating reflections and ghosting to an absolute minimum and optimizes light transmission. Naturally, all lens edges are blackened.
Screw-up eyecups allow spectacle wearers to observation with the SLV eyepieces and effectively reduce stray light.
The unique imaging characteristics of SLV eyepieces mean that they are also the ideal tool for astrophotography using a digital camera.
