The field of use ranges from aperture ratios of 1:3 to 1:15 for telescopes up to 5'' (125mm) in aperture.

It increases contrast for all Deep-Sky objects. The CLS filter improves the contrast between astronomical objects and the sky background. Thanks to its wide Full Width at Half Maximum (FWHM), a large amount of light is allowed to pass through, and stars are only slightly dampened. 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 telescopes of all diameters. Effectiveness: The filter blocks emission lines from low and high-pressure lamps (mercury (Hg) and sodium (Na)) as well as airglow lines. All emission lines from astronomical objects and the parts of the spectrum where the eye has maximum sensitivity at night are allowed to pass through. Tips for other uses: As an EOS Clip filter, it allows for DSLR photography even in conditions of high light pollution without compromising color balance. Alternatives: If there is no IR-cut filter in the case of electronic photography, a CLS-CCD filter is required. Filter characteristics: For visual observations (countryside): valid for environments with light pollution from mercury vapor lamps. For visual observations (city): valid, but a UHC-E or UHC filter is more suitable. Conventional film: excellent, white balance is excellent. CCD astrophotography: valid, but an additional IR-cut filter is required. DSLR astrophotography (unmodified): valid, some color shift but better contrast. DSLR astrophotography (modified for astronomical use): excellent, white balance is excellent. DSLR astrophotography (with clear MC glass): valid, but an additional IR-cut filter is required. Webcam \/ Video (for planets): not suitable. Webcam \/ Video (for Deep Sky): excellent, if light pollution is a serious issue. Technical data of the filter: 92% transmissivity at 486nm (H-beta), 92% transmissivity at 496nm (OIII), 92% transmissivity at 501nm (OIII), 97% transmissivity at 656nm (H-alpha). Transmissivity from 450nm to 540nm and above 650nm. Parfocal with all other astronomical filters. Filter thickness: 1mm. Moisture-resistant, non-aging, and scratch-resistant. Polished optical material. The filter is shipped in durable packaging. A small guide for selection: As a first filter, we recommend the Astronomik CLS, which cuts out 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 for viewing objects in natural colors. Important: the standard CLS filter does not have an integrated IR-blocker. Therefore, for a converted (\"astromodified\") camera, a CLS-CCD filter will be necessary! A good choice for activities in locations with very strong light pollution is the Astronomik UHC filter. The transmission curve of this filter allows only light in the H-beta, OIII, H-alpha, and SII lines to pass. The suppression 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. For in-depth astrophotography, we recommend narrowband filters for OIII, H-alpha, and SII emission lines, available with an FWHM of 6 nm or 12 nm. These filters allow for 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. For owners of converted (\"astromodified\") cameras, we suggest the Astronomik OWB filter: the acronym OWB stands for \"Original White Balance.\" The filter converts the spectrum of a modified camera, so it can also be used for daylight photography without needing to reprocess all the images.
