The filter simply screws into the 82 mm filter thread of your lens and provides high-contrast images by blocking disturbing light from street lights. This darkens the sky background and brings out the fine structures of the Milky Way better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike classic interference filters such as CLS or UHC, this filter can be used with wide-angle lenses without any problems. Interference filters require perpendicular incident light and are therefore unsuitable for extreme wide-angle shots. The Clear Sky Filter solves this and makes it easier to take beautiful widefield photos, for example of meteor swarms or the aurora.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Also in nature and macro photography, this filter has added value: red and brown tones, such as in autumn leaves or sunsets, are enhanced and better distinguished. Thanks to the special neodymium oxide glass, yellow light is effectively filtered out - an effect that can hardly be achieved in post-processing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Application<\/strong><br>The Optolong Clear Sky Filter 82 mm is ideal for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wide-angle shots of the Milky Way and star fields<\/li>\n\n\n\n<li>Astrophotography of deep-sky objects under light-polluted skies<\/li>\n\n\n\n<li>Registration of meteors and all-sky recordings<\/li>\n\n\n\n<li>Photography of aurora with more contrast and less light pollution<\/li>\n\n\n\n<li>Nature and macro photography with richer red and brown tones<\/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>Connection: 82 mm filter thread for photo lenses<\/li>\n\n\n\n<li>Mount: lens filter (threaded)<\/li>\n\n\n\n<li>Material: glass with neodymium oxide<\/li>\n\n\n\n<li>Fastening material: aluminum<\/li>\n\n\n\n<li>Design: broadband filter<\/li>\n\n\n\n<li>Optics coating: multilayer coating, plan-parallel<\/li>\n\n\n\n<li>Application: photographic use, not suitable for visual use<\/li>\n\n\n\n<li>Suitable for: galaxies, nebulae, all-sky and meteor swarms, daylight and twilight<\/li>\n<\/ul>","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=\"320\" data-end=\"758\">\u00a0<\/p>\n<p data-start=\"155\" data-end=\"318\">Optolong Clear Sky Filter 82 mm wordt geleverd met neodymiumglas, verhoogt contrast bij astrofotografie en blokkeert storend geel licht.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n","protected":false},"featured_media":28672,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[1548],"product_cat":[56,587,588],"product_tag":[],"class_list":["post-28663","product","type-product","status-publish","has-post-thumbnail","product_brand-optolong","product_cat-telescoop-accessoires","product_cat-camera-accessoires","product_cat-filters","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":28924,"url":"https:\/\/staging.telescoop.nl\/en\/optolong-filters-clear-sky-filter-77mm\/","url_meta":{"origin":28663,"position":0},"title":"Optolong Clear Sky Filter 77mm","author":"","date":"20-09-2025","format":false,"excerpt":"\u00a0 Optolong Filters Clear Sky Filter 77mm comes with aluminum mount and neodymium glass -
