Binorum Super Plössl 8mm 50° SPL 1.25″ Eyepiece
Advanced Five-Element Optical Architecture
The Super Plössl design featuring a 50° apparent field represents everyday versatility for astronomical observation - compatible with every telescope type. Modern Super Plössl eyepieces from Binorum showcase outstanding optical capabilities that transcend traditional four-element configurations. The addition of a fifth optical element enhances edge performance, reduces aberrations, and delivers contrast improvements that discerning observers immediately notice.
Exceptional Brightness and Color Accuracy
These eyepieces prove ideal for lunar and planetary observation, demonstrating the optical excellence that serious amateur astronomers demand. Distinguished by remarkable brightness and superb color rendering, they perform equally well across diverse celestial targets beyond just solar system objects. Whether you're examining Jupiter's turbulent atmosphere, tracking subtle features across the lunar terminator, or resolving star colors in open clusters, the optical precision delivers consistently impressive results.
Professional-Grade Optical Treatments
Binorum applies meticulous optical refinements throughout the Super Plössl series. Lens edges receive specialized blackening treatment to eliminate internal reflections and maintain peak contrast levels when observing bright objects. Every air-to-glass surface features FMC (Fully Multi-Coated) treatment with advanced multi-layer coatings, ensuring maximum light transmission efficiency, crisp image sharpness, and precise color fidelity. Fold-down rubber eyecups effectively shield against ambient light contamination, preserving contrast integrity during observation sessions.
The Practical 8mm Focal Length
An 8mm focal length positions this eyepiece perfectly for medium-high magnification applications across various telescope designs. With an 800mm telescope, you achieve a convenient 100x magnification - excellent for general planetary viewing and detailed lunar study. Longer instruments such as 1200mm Maksutov-Cassegrains reach 150x, ideal for examining planetary atmospheric details and resolving close double stars. The 8mm focal length provides slightly more comfortable eye relief than shorter eyepieces while maintaining the magnification needed for productive high-power observations.
