Designed specifically for Newton reflectors with an outer diameter of 138 to 153 mm, this filter fits securely over the telescope tube thanks to a clever clamping system with multiple attachment points.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The filter uses high-quality solar film that allows only a fraction of sunlight through - just enough to study sunspots, edge darkening and the grain structure of the solar surface. The image appears in a neutral grayish white, which is ideal for recognizing fine details in active solar areas. The film used meets international safety standards (ISO 12312-2), allowing you to look through your telescope with peace of mind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This model comes with adjustment rings and mounting screws, allowing you to securely mount the filter without risk of slipping. The filter is lightweight, robust and reusable - perfect for both novice and advanced solar observers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantages<\/strong><br>\u2713 Safe sunlight filter for 138-153 mm Newton telescopes<br>\u2713 Enables observation of sunspots and fringe details<br>\u2713 ISO-certified solar film - visual use without risk<br>\u2713 Easy and secure mounting via adjusting rings and screws<br>\u2713 Ideal for daily use in good sunny conditions<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Specifications<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Type:<\/strong> Solar filter for visual use<\/li>\n\n\n\n<li><strong>Suitable pipe diameter:<\/strong> 138-153 mm<\/li>\n\n\n\n<li><strong>Filter material:<\/strong> AstroSolar solar film<\/li>\n\n\n\n<li><strong>Color display:<\/strong> Neutral white\/gray<\/li>\n\n\n\n<li><strong>Attachment:<\/strong> Multiple adjusting rings + screw fixing<\/li>\n\n\n\n<li><strong>Compatibility:<\/strong> Newton reflectors and other open tube systems within reach<\/li>\n\n\n\n<li><strong>Safety:<\/strong> ISO 12312-2 certified<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observation goals<\/strong><br>The Omegon Solar Filter 138-153 mm is ideal for enthusiasts who want to use their Newton telescope for solar observation.
