A superb wide-field eyepiece offering a 40 mm focal length within a compact 1.25" barrel, it delivers a generous 43° apparent field of view—ideal for sweeping nebulae, star clusters, and large celestial vistas. Its Plöss l 4‑element design, paired with multi‑coated optics and blackened lens edges, ensures excellent light transmission, sharp contrast, and crisp imagery. Encased in durable black‑anodized aluminum with a chrome‑plated brass barrel, it features internal filter threading and a built‑in rubber eyeguard for comfortable, stray-light‑free viewing. Whether used with reflectors, refractors, or catadioptric telescopes, it consistently delivers bright, high-contrast, and visually immersive views.
