\u003cb\u003eCCD photographic filters\u003c\/b\u003e feature an integrated IR blocker, which prevents optical issues caused by infrared rays.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eMFR coating\u003c\/b\u003e: thanks to the newly developed MFR technology, the filter can be used with all devices with a focal ratio down to f\/4.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eA brief 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 suppresses a large part of light pollution and natural airglow. The result will be skies with a dark background, thus allowing longer exposure times, which makes even fainter objects visible. The filter is optimized to display objects with natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the simple 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. The reduction of background brightness is significantly greater compared to 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 \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 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

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 quick guide to 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 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 with natural colors. \u003cb\u003eImportant:\u003c\/b\u003e the standard 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 lets only light in the H-beta, OIII, H-alpha, and SII lines pass through. The reduction of background brightness is significantly greater than with a CLS; however, this filter only works with gas nebulae! Star clusters and galaxies are mostly filtered out. \u003c\/li\u003e \u003cli\u003eFor advanced astrophotography, we recommend the \u003cb\u003enarrow-band 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 you to take truly deep images of faint objects even from locations with intense light pollution and a full moon high in the sky.

Thanks to the combination of a 6nm narrow band and high 96% transmission, the filter ensures a significant increase in contrast, as all unwanted light from wavelengths other than the target is blocked from the UV to the IR. This provides an extremely dark background. \u003c\/p\u003e \u003cp\u003eThe 6 nm FWHM value is perfect for use with CCD and CMOS sensors with particularly low dark current (\u003cb\u003ecooled camera\u003c\/b\u003e). The 6 nm filters are the best choice if you are observing from a location with particularly intense light pollution or generally when shooting faint objects in areas of the sky that are very rich in stars. \u003c\/p\u003e \u003cp\u003e\u003cb\u003eFeatures\u003c\/b\u003e:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eComplete blocking of radiation from UV to infrared \u003c\/li\u003e \u003cli\u003eParfocal with all other Astronomik filters \u003c\/li\u003e \u003cli\u003eResistant to moisture, wear, and scratching \u003c\/li\u003e \u003cli\u003eOptically polished substrate free from streaks and internal stresses\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThe filter is shipped in \u003cb\u003edurable packaging\u003c\/b\u003e \u003c\/p\u003e \u003cp\u003e\u003cb\u003eTip\u003c\/b\u003e: with the H-alpha CCD and SII CCD filters, you can take emission line images in three colors (HSO) of celestial objects, just like the Hubble telescope.

This results in an \u003cb\u003eincrease in contrast\u003c\/b\u003e between the sky background and the object being observed. Due to the wide full-width at half-maximum (FWHM), the contrast is reduced compared to the UHC filter, but the greater amount of light allows it to be used profitably even with small telescopes. The transmission range of the filter includes an emission line found in the tails of comets.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTips and other modes of use\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e \u003c\/p\u003e \u003cul\u003e \u003cli\u003ePerfect for observing comets in the city with telescopes of all apertures. \u003c\/li\u003e \u003cli\u003eExperimental for the observation of Jupiter's clouds. \u003c\/li\u003e \u003cli\u003eBetter separation of double stars. \u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eand \u003c\/p\u003e \u003cp\u003eAs an EOS Clip filter, it allows you to take photographs with DSLR cameras even in conditions of high light pollution without compromising color balance. \u003c\/p\u003e \u003cp\u003e\u003cb\u003eAlternatives\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eFor telescopes from 5\" (125mm) aperture and up, we recommend the UHC filter, which increases contrast more.

Thanks to the sRGB color space defined in 1996, it is possible to maintain true colors throughout the production process, from image capture to processing and display. Monitor manufacturers, image processing software, and image rendering systems use these standards.

Thanks to its wide \u003cb\u003efull width at half maximum (FWHM)\u003c\/b\u003e, a large amount of light is allowed through, and stars are only slightly dimmed. The CLS filter is therefore primarily used to block stray light while allowing light from objects to pass through. It can be used effectively for visual observations with aperture ratios from 1:2 to 1:15 with telescopes starting from 2\" (50mm) aperture, and for CCD, DSLR, and film astrophotography with lenses and
