Lunt 27mm Flat-Field Eyepiece

• Premium flat-field optical design for sharp, edge-to-edge views—excellent for solar observing (with proper filtration), lunar cruising, and wide-field night-sky sweeps

• Ultra-low 0.1% anti-reflective coatings for maximum contrast and minimal ghosting—this is the same coating technology used on Lunt etalons for world-class performance

• High transmission and low scatter bring out delicate solar structure, subtle lunar shading, and faint star fields with ease

• Comfortable, relaxed viewing at a versatile 27 mm focal length, ideal for context-rich, “whole-scene” observations and outreach

• Precision-machined housing with glare-controlled internals for clean, high-contrast views in bright solar and dim nighttime conditions

• A smart, cost-effective upgrade to elevate the view through Lunt solar systems and compatible astronomy setups
