blocks a large part of light pollution and natural airglow. The result will be skies with a dark background and therefore longer exposure times, which make even fainter objects visible. The filter is optimized to display objects with natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the standard CLS filter does not have an integrated IR blocker. Therefore, for a converted (\"astro-modified\") camera, a CLS-CCD filter will be necessary! \u003c\/li\u003e \u003cli\u003eA good choice for activities in locations with very strong light pollution is the \u003cb\u003eAstronomik UHC\u003c\/b\u003e filter. The transmission curve of this filter allows only light in the H-beta, OIII, H-alpha, and SII lines to pass through. Background brightness reduction is significantly greater than with a CLS; however, this filter only works with gaseous nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor advanced astrophotography, we recommend \u003cb\u003enarrowband filters for OIII, H-alpha, and SII emission lines\u003c\/b\u003e, available with an FWHM of 6 nm or 12 nm. These filters allow you to take truly deep photos of faint objects even from locations with intense light pollution and a full Moon high in the sky. Shots in these narrow wavelengths do not have natural colors. \u003c\/li\u003e \u003cli\u003eFor owners of converted (\"astro-modified\") cameras, we suggest the \u003cb\u003eAstronomik OWB filter\u003c\/b\u003e: the acronym OWB stands for \"Original White Balance.\" The filter converts the spectrum of a modified camera, so it can also be used for daytime photography without having to reprocess all the images.\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain features\u003c\/h2\u003e\n\n\u003cp\u003eAstronomik quality for a reliable

SII 6nm CCD series... \u003c\/p\u003e\n\n\u003cp\u003eUnlike purely visual filters, \u003cb\u003eCCD photographic filters\u003c\/b\u003e are equipped with an integrated IR blocker, which prevents optical problems caused by infrared rays.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eMRF coating\u003c\/b\u003e: thanks to the newly designed MFRF technology, it is possible to use the filter with all devices with a focal ratio down to f\/4.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eAlternative\u003c\/b\u003e: narrow-band filters with 12 nm FWHM are interesting in combination with a DSLR or CCD camera with high dark current. The 12 nm filters are also the best choice if your camera is equipped with an integrated guiding chip, as they allow you to capture twice as many stars.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eA small guide for choosing:\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAs a first filter, we recommend the \u003cb\u003eAstronomik CLS\u003c\/b\u003e, which reduces most light pollution and natural airglow. The result will be skies with a dark background and therefore longer exposure times, which make even the faintest objects visible. The filter is optimized for viewing objects in natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the simple CLS filter does not have an integrated IR blocker. Therefore, for a converted (\"astromodified\") camera, a CLS-CCD filter will be necessary! \u003c\/li\u003e \u003cli\u003eA good choice for activities in locations with very strong light pollution is the \u003cb\u003eAstronomik UHC\u003c\/b\u003e filter. The transmission curve of this filter only allows light in the H-beta, OIII, H-alpha, and SII lines to pass through. The background brightness reduction is significantly greater than with a CLS; however, this filter only works with gaseous nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor in-depth astrophotographic use, we recommend the \u003cb\u003enarrow-band filters for OIII, H-alpha, and SII emission lines\u003c\/b\u003e, available with an FWHM of 6 nm or 12 nm. These filters allow you to take truly deep photos of faint objects even from locations with intense light pollution and a full moon high in the sky. Shots in these narrow wavelengths do not have natural colors. \u003c\/li\u003e \u003cli\u003eFor owners of converted (\"astromodified\") cameras, we suggest the \u003cb\u003eAstronomik OWB filter\u003c\/b\u003e: the acronym OWB stands for \"Original White Balance\". The filter converts the spectrum of a modified camera so that it can also be used for daytime photography, without having to reprocess all the images.\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch2

The filter is optimized to display objects in natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the standard CLS filter does not have an integrated IR block. Therefore, for a converted (\"astro-modified\") camera, a CLS-CCD filter is necessary! \u003c\/li\u003e \u003cli\u003eA good choice for activities in locations with very strong light pollution is the \u003cb\u003eAstronomik UHC\u003c\/b\u003e filter. The transmission curve of this filter allows only light in the H-beta, OIII, H-alpha, and SII lines to pass through. Background brightness suppression is significantly greater than with a CLS; however, this filter only works for gaseous nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor in-depth astrophotography, we recommend \u003cb\u003enarrowband filters for OIII, H-alpha, and SII emission lines\u003c\/b\u003e, available with an FWHM of 6 nm or 12 nm. These filters allow you to take truly deep photos of faint objects even from locations with intense light pollution and a full moon high in the sky. Shots in these narrow wavelengths do not have natural colors. \u003c\/li\u003e \u003cli\u003eFor owners of converted (\"astro-modified\") cameras, we suggest the \u003cb\u003eAstronomik OWB filter\u003c\/b\u003e: the acronym OWB stands for \"Original White Balance.\" The filter converts the spectrum of a modified camera so that it can also be used for daytime photography without having to reprocess every image.\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eKey features\u003c\/h2\u003e\n\n\u003cp\u003eAstronomik quality for a reliable and

choosing:\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAs a first filter, we recommend the \u003cb\u003eAstronomik CLS\u003c\/b\u003e, which suppresses a large part of light pollution and natural airglow. The result will be skies with a dark background and therefore longer exposure times, which make even the faintest objects visible. The filter is optimized to display objects with natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the standard CLS filter does not have an integrated IR block. Therefore, for a converted (\"astro-modified\") camera, a CLS-CCD filter is necessary! \u003c\/li\u003e \u003cli\u003eA good choice for activities in locations with very strong light pollution is the \u003cb\u003eAstronomik UHC\u003c\/b\u003e filter. The transmission curve of this filter allows only light in the H-beta, OIII, H-alpha, and SII lines to pass through. The reduction of background brightness is significantly greater compared to a CLS; however, this filter works only with gaseous nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor in-depth astrophotography, we recommend \u003cb\u003enarrowband filters for the OIII, H-alpha, and SII emission lines\u003c\/b\u003e, available with an FWHM of 6 nm or 12 nm. These filters allow for truly deep photos of faint objects, even from locations with intense light pollution and a full moon high in the sky. Shots in these narrow wavelengths do not have natural colors. \u003c\/li\u003e \u003cli\u003eFor owners of converted (\"astro-modified\") cameras, we suggest the \u003cb\u003eAstronomik OWB filter\u003c\/b\u003e: the acronym OWB stands for \"Original White Balance.\" The filter converts the spectrum of a modified camera so that it can also be used for daytime photography without needing

guide for choosing:\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAs a first filter, we recommend the \u003cb\u003eAstronomik CLS\u003c\/b\u003e, which cuts out a large part of light pollution and natural airglow. The result will be skies with a dark background, allowing for longer exposure times, which makes even fainter objects visible. The filter is optimized for viewing objects with natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the standard CLS filter does not have an integrated IR block. Therefore, for a converted (\"astro-modified\") camera, a CLS-CCD filter is required! \u003c\/li\u003e \u003cli\u003eA good choice for activities in locations with very heavy light pollution is the \u003cb\u003eAstronomik UHC\u003c\/b\u003e filter. The transmission curve of this filter allows only light in the H-beta, OIII, H-alpha, and SII lines to pass through. The reduction in background brightness is significantly greater compared to a CLS; however, this filter only works for gaseous nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor advanced astrophotography, we recommend the \u003cb\u003enarrowband filters for OIII, H-alpha, and SII emission lines\u003c\/b\u003e, available with an FWHM of 6 nm or 12 nm. These filters allow you to capture truly deep images of faint objects even from locations with intense light pollution and a full moon high in the sky. Shots in these narrow wavelengths do not have natural colors. \u003c\/li\u003e \u003cli\u003eFor owners of converted (\"astro-modified\") cameras, we suggest the \u003cb\u003eAstronomik OWB filter\u003c\/b\u003e: the acronym OWB stands for \"Original White Balance.\" The filter converts the spectrum of a modified camera, allowing it to be used for daytime photography as well, without having to reprocess every image.\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain features\u003c\/h2\u003e\n\n\u003cp\u003eAstronomik quality for a

Therefore, for a converted (\"astro-modified\") camera, a CLS-CCD filter is necessary! \u003c\/li\u003e \u003cli\u003eA good choice for activities in locations with very strong light pollution is the \u003cb\u003eAstronomik UHC\u003c\/b\u003e filter. The transmission curve of this filter allows only light in the H-beta, OIII, H-alpha, and SII lines to pass through. The reduction of background brightness is significantly greater than with a CLS; however, this filter only works with gaseous nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor in-depth astrophotography, we recommend the \u003cb\u003enarrowband filters for OIII, H-alpha, and SII emission lines\u003c\/b\u003e, available with an FWHM of 6 nm or 12 nm. These filters allow you to take truly deep photos of faint objects even from locations with intense light pollution and a full Moon high in the sky. Shots in these narrow wavelengths do not have natural colors. \u003c\/li\u003e \u003cli\u003eFor owners of converted (\"astro-modified\") cameras, we suggest the \u003cb\u003eAstronomik OWB filter\u003c\/b\u003e: the acronym OWB stands for \"Original White Balance.\" The filter converts the spectrum of a modified camera, so you can also use it for daytime photography without having to reprocess all the images.\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eKey features\u003c\/h2\u003e\n\n\u003cp\u003eAstronomik quality for a reliable and
