It attenuates the effects of light pollution and thus increases the contrast between the celestial object being photographed and the background sky.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe broadband filter blocks Na (sodium) and Hg (mercury) wavelengths mainly emitted by urban night lighting or undesirable natural light (atmospheric oxygen radiation, etc.), while allowing the main wavelengths from celestial objects.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe anti-light pollution filter is particularly useful for improving the brightness of deep sky objects: nebulae, star clusters, galaxies, etc. It is especially effective on emission nebulae because of the filtered wavelengths.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eExamples of emission nebulae: Bubble (NGC 7635), Crescent (NGC 6888), Eagle (M16), Elephant’s Trunk (IC 1396), Flame (NGC 2024), Lagoon (M8), North America (NGC 7000), Omega (M17), Orion (M42), Pacman (NGC 281), Rosette (NGC 2237), Tarantula (NGC 2070), Thor’s Helmet (NGC 2359), Trifid (M20), Tulip (Sh2-101).\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eDesigned specifically for the Vespera lens, it fits easily and discreetly into the optical arm. The lens ring that holds the CLS filter is equipped with an electronic card that allows Vespera to detect it.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe filter is delivered in a transparent storage box.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eTransmission curve\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003ca href=\"https:\/\/vaonis.com\/wp-content\/uploads\/2022\/07\/Courbe-filtre-cls.png\" data-rel=\"lightbox-image-0\" data-rl_title=\"\" data-rl_caption=\"\" title=\"\" data-mce-fragment=\"1\"\u003e\u003cimg height=\"300\" width=\"777\" src=\"https:\/\/vaonis.com\/wp-content\/uploads\/2022\/07\/Courbe-filtre-cls.png\" alt=\"Vespera light pollution filter transmission curve\" data-mce-fragment=\"1\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"box-sizing: border-box;
