Astronomik CLS Clip-Filter EOS M (Astronomik, SKU: 10204082 / 8h00r6) is a light pollution suppression filter designed for imaging nebulae, galaxies and star clusters with photographic lenses. It enhances the contrast between deep-sky objects and the night sky by completely blocking sodium (Na) and mercury (Hg) vapor lamp emissions as well as natural airglow, while transmitting most of the visible light and nebular emissions.

Key features

• effective light pollution reduction
• increased contrast of nebulae, galaxies and star clusters
• complete blocking of sodium (Na) and mercury (Hg) vapor lamp emissions and natural airglow
• wide transmission range resulting in minimal star attenuation
• transmits most visible light and nebular emissions
• designed for mirrorless and DSLR cameras
• requires an additional IR-block filter if the camera has no built-in IR-cut filter
• compatible with photographic lenses and telescopes
• parfocal with other Astronomik filters
• diffraction-limited design – no loss of resolution or contrast
• strict quality control
