Binorum Super Plössl 10mm 50° SPL 1.25″ Eyepiece
The Perfect Upgrade from Standard Telescope Eyepieces
The Binorum Super Plössl 10mm eyepiece represents an ideal replacement for the standard eyepieces supplied with most entry-level and mid-range telescopes. Many telescopes come equipped with basic eyepieces that deliver acceptable but unremarkable performance. Upgrading to this Super Plössl immediately reveals details and clarity that stock eyepieces simply cannot match, transforming your observing experience without requiring a new telescope.
Superior Optical Design for Everyday Astronomy
Featuring a practical 50° apparent field of view and advanced Super Plössl construction, this eyepiece suits every telescope type from refractors to reflectors and catadioptric systems. Modern Super Plössl eyepieces from Binorum deliver outstanding optical performance through their sophisticated 5-element design, surpassing conventional 4-element configurations in edge sharpness and contrast delivery.
Optimized for Solar System Observation
These eyepieces excel at lunar and planetary observation, where their exceptional brightness and superior color fidelity bring celestial targets to life. The optical refinements ensure that Jupiter's atmospheric bands, Saturn's ring divisions, and lunar crater details appear with remarkable clarity and natural color balance. The versatility extends beyond planets - globular clusters, double stars, and bright nebulae all benefit from the enhanced optical quality.
Professional Optical Refinements
Every Super Plössl eyepiece incorporates carefully engineered features. Blackened lens edges eliminate internal reflections that compromise contrast when viewing bright objects. All optical surfaces receive FMC (Fully Multi-Coated) treatment with specialized multi-layer coatings ensuring excellent light transmission, razor-sharp image definition, and accurate color reproduction. Rubber fold-down eyecups shield against ambient light intrusion while accommodating both eyeglass wearers and bare-eye observers.
Versatile 10mm Focal Length
At 10mm focal length, this eyepiece occupies the sweet spot for medium-power observations. With a 1000mm telescope, it delivers 100x magnification - perfect for detailed lunar exploration and comprehensive planetary viewing. Shorter focal length instruments around 500-600mm reach 50-60x, excellent for wide-field lunar views and bright deep-sky objects. The 10mm focal length provides comfortable eye relief while delivering sufficient magnification for productive planetary work.
