Lunt Solar Systems 1.25" 7.2mm - 21.5mm zoom eyepiece (17812)

The Zoom Eyepiece 7.2mm - 21.5mm from Lunt Solar Systems is crafted to deliver exceptional optical performance, especially for solar observation. Designed to complement Lunt telescopes, this eyepiece provides sharp, high-contrast views of the Sun and also excels when used for nighttime astronomy. Its optical design focuses on minimizing internal reflections through advanced thin-film multicoatings, an internal baffle system, and blackened lens edges. While it does not offer the widest field of view, it prioritizes image quality and correction across the entire field. The eyepiece is nearly parfocal throughout its zoom range, requiring less than 0.5 mm of refocusing. A multi-height adjustable eyeguard adds comfort and helps block stray light for an improved viewing experience.
