Thanks to the multilayer dielectric coating with 99% reflection, you hardly lose any light. That means up to 10% brighter images than with standard aluminum-coated mirrors - ideal for deep-sky objects and subtle planetary details.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 90\u00b0 viewing angle makes observing comfortable even when objects are high in the sky. The mirror delivers a sharp, high-contrast image and utilizes the full aperture of your telescope. Even wide-angle 2\u201d eyepieces are fully exposed, without vignetting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mechanically, the zenith mirror is robustly built with black-silver finish. Eyepieces are secured securely and scratch-free with the ring clamp. In addition, a 2\u201d to 1.25\u201d adapter is included so you can also use your existing 1.25\u201d eyepieces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A dielectric coating is not only brighter, but also more durable: the reflection layer does not wear out when cleaned and maintains the same performance for years.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Application<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ideal for astronomical observations of the moon, planets and deep-sky objects, where brightness and contrast are of great importance. Not suitable for terrestrial observations, as the image remains mirrored.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Type: zenith mirror (star diagonal \/ star diagonal)<\/li>\n\n\n\n<li>Viewing angle: 90\u00b0<\/li>\n\n\n\n<li>Telescope connection: 2\u201d<\/li>\n\n\n\n<li>Ocular connection: 2\u201d with ring clamp + 1.25\u201d adapter<\/li>\n\n\n\n<li>Optics coating: dielectric, 99% reflection<\/li>\n\n\n\n<li>Image orientation: upright, left-right mirrored<\/li>\n\n\n\n<li>Weight: 480 g<\/li>\n\n\n\n<li>Dimensions: 13 \u00d7 6.8 \u00d7 9 cm<\/li>\n\n\n\n<li>Material: aluminum + carbon elements<\/li>\n\n\n\n<li>Color: black-silver<\/li>\n\n\n\n<li>Series: Pro<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p data-start=\"400\" data-end=\"502\">Omegon Zenith mirror 90\u00b0 2 inch 99% dielectric -
