In addition to typical light pollution sources (sodium and mercury vapor lamps, skyglow), this variant also blocks infrared waves from <strong>700-1100 nm<\/strong>. This makes this filter ideal for modified DSLRs and CCD color cameras, where IR light often lands unwanted on the sensor and leads to blur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CLS-CCD allows the primary emission lines of nebulae - OIII (496\/500 nm), H-beta (486 nm), NII (654\/658 nm), H-alpha (656 nm) and SII (672 nm) - to pass through without loss. This increases contrast and makes fainter details visible, such as the outer edges of emission and planetary nebulae. Supernova remnants also benefit from the additional IR filtering.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, compared to the standard CLS filter, the CLS-CCD provides an even cleaner signal and better color neutrality in astrophotography with modified cameras. For those shooting under urban or suburban skies, this provides a noticeable improvement in image quality and contrast.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observation goals<\/strong><br>The Optolong CLS-CCD Clip Filter Canon EOS APS-C is ideal for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deep-sky photography with <strong>modified Canon EOS APS-C DSLRs<\/strong><\/li>\n\n\n\n<li>Use with CCD color cameras sensitive to IR light<\/li>\n\n\n\n<li>Photography of emission nebulae, planetary nebulae and supernova remnants<\/li>\n\n\n\n<li>Improving contrast and visibility of fainter details at the edges of nebulae<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Specifications<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Suitable for: Canon EOS APS-C (modified DSLRs) and CCD cameras<\/li>\n\n\n\n<li>Material: shot glass<\/li>\n\n\n\n<li>Mount: clip-in (1.25\u2033 equivalent size)<\/li>\n\n\n\n<li>Type: broadband filter (CLS-CCD)<\/li>\n\n\n\n<li>Optics coating: multi-coated<\/li>\n\n\n\n<li>Transmission: approx. 80%<\/li>\n\n\n\n<li>Surface accuracy: \u03bb\/4<\/li>\n\n\n\n<li>Application: photographic and visual<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Note<\/strong><br>This filter should never be used as the sole sunscreen.<\/p>","protected":false},"excerpt":{"rendered":"<article class=\"w-full text-token-text-primary focus-visible:outline-2 focus-visible:outline-offset-[-4px]\" dir=\"auto\" data-testid=\"conversation-turn-35\" data-scroll-anchor=\"true\">\n<div class=\"text-base my-auto mx-auto py-[18px] px-6\">\n<div class=\"mx-auto flex flex-1 text-base gap-4 md:gap-5 lg:gap-6 md:max-w-3xl lg:max-w-[40rem] xl:max-w-[48rem]\">\n<div class=\"group\/conversation-turn relative flex w-full min-w-0 flex-col agent-turn @xs\/thread:px-0 @sm\/thread:px-1.5 @md\/thread:px-4\">\n<div class=\"flex-col gap-1 md:gap-3\">\n<div class=\"flex max-w-full flex-col flex-grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 whitespace-normal break-words text-start [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"28a009d2-3136-4224-8ee5-30c9a1a2ece5\" data-message-model-slug=\"gpt-4o\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose w-full break-words dark:prose-invert dark\">\n<p data-start=\"379\" data-end=\"867\">\u00a0<\/p>\n<p data-start=\"181\" data-end=\"377\">Optolong CLS-CCD Clip Filter Canon EOS APS-C wordt geleverd met breedbandcoating en extra IR-blokkade voor contrastrijke deep-sky fotografie met gemodificeerde camera\u2019s.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n","protected":false},"featured_media":28694,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[1548],"product_cat":[588,587,3139,56],"product_tag":[],"class_list":["post-28687","product","type-product","status-publish","has-post-thumbnail","product_brand-optolong","product_cat-filters","product_cat-camera-accessoires","product_cat-lichtvervuilingsfilters-light-pollution","product_cat-telescoop-accessoires","product_shipping_class-licht","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":104875,"url":"https:\/\/www.telescoop.nl\/en\/levenhuk-labzz-t3\/","url_meta":{"origin":28687,"position":0},"title":"Levenhuk LabZZ T3 - 60\/700 Refractor","author":"Abdullah Ibrar","date":"24-03-2026","format":false,"excerpt":"Levenhuk LabZZ T3 - 60\/700 Refractor comes with 4mm eyepiece, 12.5mm eyepiece, 1.5x eyepiece, 3x Barlow lens, 5x optical viewfinder, zenith mirror and aluminum tripod with accessory tray.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"Levenhuk LabZZ T3 - 60\/700 Refractor aluminium statief met accessoirebak","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/03\/Levenhuk-LabZZ-T3-60700-Refractor-1.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":105543,"url":"https:\/\/www.telescoop.nl\/en\/levenhuk-skyline-travel-70\/","url_meta":{"origin":28687,"position":1},"title":"Levenhuk Skyline Travel 70 - 70\/400 Refractor","author":"Abdullah Ibrar","date":"03-04-2026","format":false,"excerpt":"The Levenhuk Skyline Travel 70 \u2013 70\/400 Refractor comes with 10mm and 20mm eyepieces, a 3x Barlow lens, a 5x24 finderscope, a diagonal prism, an aluminum tripod, and a backpack.
