SP series eyepieces set the performance standard for modern telescope oculars. The proven 4-element Plössl, with edge-to-edge blackened elements, delivers the highest contrast images attainable. SP series eyepieces minimize spherical aberration, distortion, astigmatism and off-axis colour, while the oversize optical elements afford the observer luxurious eye relief. Stray light is eliminated by the fold back rubber eyecups standard with every SP eyepiece. The focal length available at 40mm, 32mm, 17mm, 12.5mm and 7.5mm.
