To the category: Eyepieces for telescopes / 50 SERIES
SIGETA 50 SERIES 25mm is a low-power survey eyepiece based on a 4-lens Plössl design. With its 25mm focal length, it provides optimal magnification for observing deep space objects - from majestic nebulae to open star clusters and galaxies. The moderate 50-degree field of view combined with a comfortable 18mm eye relief makes extended observations particularly convenient.
The classic 4-element design is enhanced with modern multi-layer coating on all optical surfaces, ensuring maximum light transmission and formation of high-contrast images with natural colors. The fold-down rubber eyecup not only improves observation comfort but also effectively protects against stray light.
The SIGETA 50 SERIES 25mm eyepiece uses a universal 1.25-inch mounting format for maximum compatibility with a wide range of telescopes. The metal housing with non-slip rubber grips provides secure handling, while internal threading allows for installation of compatible astronomical filters.
