This broadband filter suppresses the wavelengths of sodium and mercury lighting, making the background of the sky darker and helping nebulae stand out better from that gray glow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The filter allows a broader portion of the spectrum to pass through than a UHC or OIII filter. As a result, the image retains its natural colors and brightness, while the contrast of emission nebulae and planetary nebulae is enhanced. For those observing from the city or the outskirts of a village, this is the most affordable way to upgrade.<\/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\/08\/Omegon-Filters-Nevelfilter-Pollutiefilter-1-25-.jpg\" alt=\"Omegon nebula and city light filter 1.25 inch\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Filters-Nevelfilter-Pollutiefilter-1-25-1.jpg\" alt=\"Omegon nebula and city light filter 1.25 inch\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Filters-Nevelfilter-Pollutiefilter-1-25-2.jpg\" alt=\"Omegon nebula and city light filter 1.25 inch\" title=\"\"><\/figure><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Broadband rejection filter for sodium and mercury lighting<\/li><li>Passes the OIII and H-beta lines, keeping nebulae visible<\/li><li>Retains natural star colors, no strong color cast<\/li><li>Standard 1.25 inch thread<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Screws onto the filter thread of any standard 1.25-inch eyepiece.
