Just imagine enhancing your stargazing experience with the Alpine Astronomical Baader 18mm Classic Ortho Eyepiece, a high-quality and durable addition to your astronomy equipment. This user-friendly eyepiece boasts a generous 52-degree apparent angle of view, delivering a wide field of view and relatively low magnification across a variety of optical tube assemblies (OTAs). Designed to be parfocal with other Ortho eyepieces, this innovative product minimizes the need for refocusing when switching eyepieces within the Ortho line, saving you valuable observation time. Its sophisticated 4-element/2-group lens design, featuring a triplet-element and a single plano-convex eye lens, ensures only four glass-air surfaces are present, effectively reducing internal diffraction and light loss. The Baader Classic Ortho 18mm Eyepiece stands out with its High-Transmission (HT) multi-coatings applied to all glass-air surfaces. This advanced feature enhances image brilliance while virtually eliminating internal reflections, resulting in a pure-white image that boasts improved sharpness and contrast. The interior of the anodized housing is meticulously blackened to suppress stray light, further enhancing image clarity. It also features machined threads that accept most standard 1.25" filters, making it a versatile addition to your observational kit. Designed with compatibility in mind, this eyepiece comes with a standard 1.25" barrel, fitting seamlessly with most popular-sized holders and accessories. The inclusion of a winged eyecup serves to block stray terrestrial light, improving brightness and contrast while eliminating distractions, making your celestial viewing experience more immersive. In summary, the Alpine Astronomical Baader 18mm Classic Ortho Eyepiece is a reliable, innovative, and user-friendly choice for astronomy enthusiasts seeking to enhance their exploration of the cosmos.
