Omegon Eyepiece Cronus WA 4 mm 1.25\u2033 - High magnification for sharp planetary detail<\/strong><\/h3>\n\n\n\n

The Omegon Eyepiece Cronus WA 4 mm 1.25\u2033<\/strong> is a powerful wide-angle eyepiece for observers seeking razor-sharp detail at high magnifications. This planetary eyepiece<\/strong> has a wide 60\u00b0 field of view<\/strong>, which ensures stable and comfortable vision even during long observations. The eye relief of 16 mm<\/strong> also makes it suitable for eyeglass wearers.<\/p>\n\n\n\n

Thanks to the multiple optics coating<\/strong> and the optimized anti-glare design, this eyepiece minimizes reflections and provides a clear and contrasty image. This makes it perfect for telescopes with a 1.25-inch mount<\/strong>, such as Newton reflectors, refractors and Schmidt-Cassegrain telescopes.<\/p>\n\n\n\n

What can you see with it?<\/strong><\/h4>\n\n\n\n

\u2713 Fine cloud structures and the Great Red Spot on Jupiter<\/strong>
\u2713 The rings of Saturn<\/strong>, including the Cassini separation
\u2713 Surface details on Mars<\/strong>, such as polar caps and dust storms
\u2713 Crisp details on the Moon<\/strong>, such as craters and rills
\u2713 Compact deep-sky objects such as planetary nebulae and binary stars<\/p>\n\n\n\n

Key features<\/strong><\/h4>\n\n\n\n
    \n
  • Focal length:<\/strong> 4 mm - ideal for high magnifications<\/li>\n\n\n\n
  • 1.25-inch mount<\/strong> - Fits most telescopes without an adapter<\/li>\n\n\n\n
  • Planetary eyepiece<\/strong> - Optimized for maximum sharpness and contrast<\/li>\n\n\n\n
  • 60\u00b0 field of view<\/strong> - Wider viewing angle for comfortable observation<\/li>\n\n\n\n
  • 16 mm eye relief<\/strong> - suitable for eyeglass wearers<\/li>\n\n\n\n
  • Multiple optics coating<\/strong> - increases light transmission and reduces reflections<\/li>\n\n\n\n
  • Anti-stray light design<\/strong> - Minimizes stray light for better contrasts<\/li>\n\n\n\n
  • Adjustable eye cup<\/strong> - prevents stray light and improves viewing comfort<\/li>\n\n\n\n
  • Filter thread<\/strong> - Compatible with 1.25-inch color and moon filters<\/li>\n<\/ul>\n\n\n\n
