Then you simply mount your lens or telescope adapter: the filter protects the sensor and filters every image you take. This CLS filter (City Light Suppression) blocks the disruptive emission lines of street lighting, while allowing the light from nebulae and galaxies to pass through.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The result under a city sky: a darker background, more contrast, and longer usable exposure times before light pollution overwhelms the image.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/09\/Optolong-Filters-Clip-Filter-for-Canon-EOS-APS-C-CLS.jpg\" alt=\"Optolong CLS clip filter for Canon EOS APS-C\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/09\/Optolong-Filters-Clip-Filter-for-Canon-EOS-APS-C-CLS-1.jpg\" alt=\"Optolong CLS clip filter for Canon EOS APS-C\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/09\/Optolong-Filters-Clip-Filter-for-Canon-EOS-APS-C-CLS-2.jpg\" alt=\"Optolong CLS clip filter for Canon EOS APS-C\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Click and shoot<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The filter is installed and removed without tools and does not affect camera functions.
