Astronomik CLS CCD Clip-Filter EOS M (Astronomik, SKU: 10204083 / 8h00r7) is a light pollution suppression filter designed for deep-sky astrophotography. Developed for cameras intended for astronomical use, it significantly enhances the contrast between deep-sky objects and the sky background, making it ideal for imaging under light-polluted urban and suburban skies.
• effective light pollution reduction
• increased contrast of deep-sky objects
• complete blocking of sodium (Na) and mercury (Hg) vapor lamp emissions and natural airglow
• wider transmission range compared to UHC filters, resulting in less star attenuation
• integrated infrared (IR) blocking layer
• suitable for cameras without a built-in IR-cut filter
• compatible with mirrorless, DSLR, CMOS and CCD cameras
• usable with optics from f/1.8 to f/15
• very good light pollution suppression for CMOS and CCD imaging
• very good color balance for astro-modified and MC-modified DSLR cameras
• parfocal with other Astronomik filters
• diffraction-limited design – no loss of resolution or contrast
• strict quality control
• Astronomik CLS CCD Clip-Filter EOS M
• high-quality, durable filter storage box
• 95% transmission at 486nm (H-beta)
• 95% transmission at 496nm (OIII)
• 95% transmission at 501nm (OIII)
• 97% transmission at 656nm (H-alpha)
• transmission range: 450–520nm and 640–690nm
• usable focal ratio range: f/1.8 to f/15
• glass thickness: 1mm
• finely polished optical glass free from streaks, internal stress and bubbles
• coating: Astronomik MFR
• fully resistant to high humidity and aging effects
The CLS CCD filter enables high-contrast imaging of nebulae, galaxies and other deep-sky objects even under heavy light pollution while maintaining high transmission of key astronomical emission lines.
