Lunt Flat Field 27mm Eyepiece - 1.25"
The Lunt 27mm Flat-Field Eyepiece provides comfortable, low-power views with a wider field that makes it easy to take in the full solar disk and larger celestial targets. Its flat-field optical design helps maintain sharpness across the field, while premium 0.1% anti-reflective coatings—the same coatings Lunt uses on its solar etalons—help minimize reflections and improve contrast. With its longer 27mm focal length, it’s an excellent choice for relaxed solar viewing, object locating, and general astronomical observing.
