The red color makes subtle structures more visible, such as polar caps, dust storms and dark areas on the Martian surface. In addition, the filter can also be used for visual observation of the moon at low altitude or when the moonlight is bright.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The filter mount is made of precision machined anodized aluminum. With a very thin profile, this mount prevents shadowing and diffraction. The glass is completely homogeneous and multi-coated to ensure clear and high-contrast image quality. Thanks to the double thread, the filter can be combined with other filters. The filter comes in a sturdy protective box.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Filter type:<\/strong> Light red color filter #23A<\/li>\n\n\n\n<li><strong>Format:<\/strong> 1.25 inch thread<\/li>\n\n\n\n<li><strong>Material mount:<\/strong> Anodized aluminum<\/li>\n\n\n\n<li><strong>Optics coating:<\/strong> Multiple<\/li>\n\n\n\n<li><strong>Usage:<\/strong> Visual and photographic observation<\/li>\n\n\n\n<li><strong>Series:<\/strong> Basic<\/li>\n\n\n\n<li><strong>Compatible with:<\/strong> 1.25\u2033 eyepieces and filter wheels<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Application<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With this filter you see:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mars: dust storms, polar caps and surface contrasts<\/li>\n\n\n\n<li>Moon: more structure and contrast with bright exposure<\/li>\n\n\n\n<li>Daytime: can be used for observing planets in twilight and daylight (with telescope restrictions)<\/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<h3 data-start=\"345\" data-end=\"374\">\u00a0<\/h3>\n<p data-start=\"211\" data-end=\"343\">Lichtrood kleurfilter 1,25 inch \u2013 Omegon #23A helpt om details op Mars en andere planeten zichtbaar te maken dankzij sterk contrast.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n","protected":false},"featured_media":24875,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[56,587,588,3140],"product_tag":[],"class_list":["post-24870","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-telescoop-accessoires","product_cat-camera-accessoires","product_cat-filters","product_cat-maan-en-planetenfilters-kleurfilters","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":24888,"url":"https:\/\/staging.telescoop.nl\/en\/donkerblauw-kleurfilter-125-inch-omegon-38a\/","url_meta":{"origin":24870,"position":0},"title":"Dark blue color filter 1.25 inches -
