SVBONY 15mm 66 Degree Ultra Wide Angle Eyepiece Bundle

A 15mm focal length eyepiece is well-suited for observing the lunar surface, planets, binaries, and bright nebulae. This intermediate eyepiece features a multi-lens design with 4 lenses in 3 groups, which enhances optical performance by delivering sharp images with good color correction and contrast.

The 16mm eye relief provides a comfortable viewing distance, allowing eyeglass wearers to see the entire field of view without the need for specialized positioning. The fully multi-coated optics and 4-element, 3-group lens configuration enable more light to pass through the eyepiece, resulting in brighter, sharper, and higher-contrast images.

The rubber eye cup eliminates the need for users to adjust their eye placement to see the full field of view, making it comfortable for both eyeglass wearers and those with long eyelashes.

The eyepiece boasts an ultra-wide 66-degree apparent field of view, which is well-suited for observing the lunar surface, planets, binaries, star clusters, and the Milky Way. The fully multi-coated (FMC) lens coating and 5-element, 3-group lens design maximize light transmission, minimize internal reflections, and enhance contrast, providing crisp and detailed images.

The internal blackening of the optics helps to eliminate light scattering, further minimizing internal reflections and maximizing contrast. The aluminum 1.25-inch eyepiece barrel is also internally blackened to reduce light scattering, and it is threaded to accept 1.25-inch filters.

The 66-degree apparent field of view makes this eyepiece well-suited for a wide range of astronomical observations, from broad field lunar observations to medium-sized star clusters and a variety of deep-sky targets, all with exceptional sharpness and clarity.
