Binorum Super Plössl 12mm 50° SPL 1.25″ Eyepiece
Versatile Medium-Power Performance
The Super Plössl eyepiece construction with a 50° field of view offers everyday versatility - suitable for every telescope. Binorum Super Plössl eyepieces represent modern Plössl designs with outstanding optical performance that elevate visual astronomy beyond what conventional eyepieces can deliver. The 12mm focal length occupies a strategic position in any eyepiece collection, providing the perfect balance between magnification and field coverage for a wide range of astronomical targets.
Exceptional Image Quality Across All Targets
These eyepieces prove ideal for observing the Moon and planets, where their performance characteristics truly shine. Distinguished by remarkable brightness and excellent color rendition, they perform equally well across diverse celestial objects beyond just solar system targets. Whether examining intricate lunar crater systems, tracking cloud features on Jupiter, or resolving stars in open clusters, the optical precision delivers consistently impressive results that enhance your connection with the cosmos.
Premium Optical Engineering
The lens edges of these Super Plössl eyepieces have been blackened to ensure optimal contrast and suppress stray light reflections. Special FMC (Fully Multi-Coated) multi-layer treatments on all optical surfaces guarantee excellent light transmission, image sharpness, and accurate color fidelity. These professional-grade coatings minimize light loss and eliminate ghosting, ensuring maximum performance whether you're observing bright planets or faint deep-sky objects. Rubber fold-down eyecups protect against scattered ambient light while providing comfortable viewing for extended observation sessions.
The All-Purpose 12mm Focal Length
At 12mm focal length, this eyepiece serves as an excellent general-purpose tool that handles multiple observing scenarios with equal competence. With a 600mm telescope, it provides 50x magnification - perfect for wide-field lunar views and large star clusters. Paired with a 1200mm instrument, you achieve 100x magnification, ideal for detailed planetary observation and lunar crater studies. The moderate magnification makes it forgiving of less-than-perfect atmospheric conditions while still revealing substantial detail on solar system objects.
Comfortable Eye Relief
The 12mm focal length provides approximately 8-9mm of eye relief, making it comfortable for most observers during extended viewing sessions. This generous eye relief allows relaxed eye positioning without the need to press your eye tightly against the eyepiece, reducing fatigue during long nights at the telescope. The comfortable viewing experience makes this an eyepiece you'll reach for repeatedly.

Wide Range of Observing Applications
The 12mm Super Plössl excels as a multi-purpose eyepiece suitable for numerous astronomical pursuits. Lunar observers appreciate its ability to frame substantial portions of the Moon while still revealing detailed crater formations and surface features. Planetary enthusiasts find it delivers useful magnification for observing atmospheric phenomena on Jupiter and Saturn's ring system. The eyepiece also performs admirably on brighter deep-sky objects including open star clusters, large globular clusters, and emission nebulae, making it one of the most versatile focal lengths available.
Superior to Standard 4-Element Designs
The 5-element Super Plössl construction provides meaningful advantages over traditional 4-element Plössl eyepieces: improved edge-to-edge sharpness, enhanced color correction throughout the field, reduced internal reflections through optimized element spacing, and better contrast on subtle planetary features. The blackened lens edges work in conjunction with the FMC coatings to deliver exceptional image quality that rivals significantly more expensive eyepiece designs.
