Many lenses and optical systems allow infrared light to pass through while it is not focused on the same focal plane as visible light. The result: blur, color cast or loss of detail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With this filter, all light above about 700 nanometers - the infrared spectrum - is actively blocked. This provides a sharper image and prevents chromatic distortion or halo effects around bright stars. Especially in astrophotography with color cameras without built-in IR-cut, this filter is essential. Visual observation with APO refractors or ED lenses can also improve the image by reducing color errors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The filter fits any 1.25\u2033 eyepiece, camera adapter or filter wheel. The glass is multi-coated and carefully ground for minimal reflections and maximum transmission of visible light.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantages<\/strong><br>\u2713 Blocks infrared light (from ~700 nm)<br>\u2713 Improves sharpness and color in photography<br>\u2713 Prevents chromatic distortion in visual use<br>\u2713 Ideal for cameras without an internal IR-cut filter<br>\u2713 Fits all 1.25\u2033 accessories and filter wheels<\/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> Infrared blocking filter<\/li>\n\n\n\n<li><strong>Connection:<\/strong> 1.25 inches (31.75 mm)<\/li>\n\n\n\n<li><strong>Transmission:<\/strong> High within 400-700 nm, blocking above that<\/li>\n\n\n\n<li><strong>Mounting:<\/strong> Aluminum, black anodized with fine threads<\/li>\n\n\n\n<li><strong>Coating:<\/strong> Multiple anti-reflective<\/li>\n\n\n\n<li><strong>Application:<\/strong> Astrophotography and visual use with APOs or ED refractors<\/li>\n\n\n\n<li><strong>Not suitable for:<\/strong> Narrowband applications or emission line insulation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Application<\/strong><br>The Omegon Blocking Filter Infrared Filter 1.25\u2033 is ideal for astrophotographers working with color cameras without integrated IR cut and for visual observers who experience hindrance from color cast or blur.
