Meade Series 4000 Eyepiece and Filter Set - Designed and manufactured to exacting standards, Meade Series 4000 Super Plossl eyepieces deliver wide 52° apparent fields of view with all of the resolution, edge-of-field sharpness and color correction demanded in the most advanced visual applications.
The world standard in telescope oculars, Meade Series 4000 eyepieces yield the widest possible fields of view, consistent with pinpoint edge-of-field sharpness and long eye relief - and yet with extremely low astigmatism, spherical aberration, and off-axis color.
Incorporating 7-layer multi-coatings and edge-blackened optics for optimum image contrast, these sophisticated 4-element designs permit levels of optical performance generally impossible to achieve with eyepieces of fewer elements.
