Unlike narrowband filters, it doesn't isolate a single spectral line but selectively cuts stray light sources, leaving the color balance of broadband subjects like galaxies and star clusters largely unchanged.\u003c\/p\u003e\u003ch3\u003eAlso effective against natural airglow\u003c\/h3\u003e\u003cp\u003eIn addition to artificial light pollution, the NGS1 filter also reduces airglow, the natural glow of the upper atmosphere generated by the recombination of oxygen and nitrogen after exposure to solar UV rays. This phenomenon becomes especially visible in shots taken from high-altitude observing sites under very dark skies, where the NGS1 filter offers a concrete advantage over an unfiltered sensor.\u003c\/p\u003e\u003ch3\u003eDesigned for fast optics\u003c\/h3\u003e\u003cp\u003eLike all IDAS interference filters, the spectral cutoff was designed to remain stable even at the wide angles of incidence typical of very fast photographic optics, thanks to IGAD coating technology.\u003c\/p\u003e\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\u003cth\u003eParameter\u003c\/th\u003e\u003cth\u003eValue\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eTransmission\u003c\/td\u003e\u003ctd\u003e97%\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eGlass thickness\u003c\/td\u003e\u003ctd\u003e2.5 mm\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eMount\u003c\/td\u003e\u003ctd\u003eClip filter\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eMount material\u003c\/td\u003e\u003ctd\u003eAluminium\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCompatibility\u003c\/td\u003e\u003ctd\u003eCanon EOS APS-C\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eInfrared blocking\u003c\/td\u003e\u003ctd\u003eYes\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eConstruction type\u003c\/td\u003e\u003ctd\u003eCLS broadband filter\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eSeries\u003c\/td\u003e\u003ctd\u003eLPS-D3\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePhotographic use\u003c\/td\u003e\u003ctd\u003eYes\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLight pollution reduction\u003c\/td\u003e\u003ctd\u003eYes\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eSuitable for nebulae and galaxies\u003c\/td\u003e\u003ctd\u003eYes\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eVisual use\u003c\/td\u003e\u003ctd\u003eNo (photographic only)\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWho it's recommended for\u003c\/h2\u003e\u003cp\u003eSuitable for those shooting with an unmodified Canon EOS APS-C camera body who want to reduce the impact of urban light pollution without altering the sky's natural colors.
