The 1.25" diameter barrel Meade Series 4000 Super Plossl Eyepiece yields a wide consistent viewing field with edge-of-field sharpness and long eye relief - and it does so while boasting extremely low astigmatism, spherical aberration, and off-axis color. Incorporating 7-layer multicoatings and edge-blackened optics for optimum image contrast, this sophisticated 4-element ocular delivers an excellent level of optical performance.
Like all Series 4000 eyepieces, this 40mm Super Plossl includes a soft rubber eyeguard with a bayonet mount. The eyeguard folds down and it shields eyeglasses from coming into contact with the metal housings.
