Lunt 16mm Flat-Field Eyepiece

• Purpose-built for clean, high-contrast views in solar setups—perfect for full-disk H-alpha, CaK, and white-light observing

• Ultra-low scatter optics: coated with 0.1% anti-reflective layers (the same coatings used on Lunt etalons) to preserve fine detail in filaments, plages, and sunspot structure

• Flat-field design keeps the image sharp and level toward the edge—great for lunar cruising and rich-field star sweeps after sunset

• Neutral, color-faithful performance and a crisp snap-to-focus feel for confident fine tuning

• Robust, observatory-friendly build that travels well for outreach or grab-and-go sessions
