Lunt 12mm Flat-Field Eyepiece

• High-contrast flat-field design keeps the entire view tack-sharp—perfect for resolving fine solar structure (with proper filtration), lunar details, and tight planetary features

• Ultra-low 0.1% anti-reflective coatings for maximum light transmission and minimal ghosting—the same coating technology used on Lunt etalons for premium performance

• 12 mm focal length hits the sweet spot for medium-to-high magnification, revealing filaments, plages, sunspot penumbrae, and delicate tonal gradations

• Excellent scatter control and glare management for clean, high-contrast views in bright solar and dim night-sky conditions

• Precision-machined housing with smooth insertion and secure clamping for consistent collimation and repeatable focus

• A focused, cost-effective upgrade that elevates both solar (with appropriate filters) and general visual observing on compatible setups

• Optimized to pair seamlessly with Lunt blocking filters and modules, and broadly compatible with standard astronomy gear
