Astronomik CLS XT Clip-Filter EOS APS-C (Astronomik, SKU: 10203082 / 8h00ke) is designed for imaging nebulae, galaxies, and star clusters with photographic lenses. It completely blocks emission lines from high- and low-pressure sodium (Na) and mercury (Hg) lamps as well as natural airglow, while transmitting most visible light and nebular emissions.
This significantly enhances the contrast between deep-sky objects and the night sky background, making the filter highly suitable for astrophotography under light-polluted conditions.
Thanks to its wide transmission range, star attenuation is minimal. The filter is optimized to block as much unwanted light as possible while allowing maximum transmission of astronomical object light.
• 1.25" and 2" mounted versions can be used for visual observation from light-polluted areas
• Astronomik CLS CCD – required for cameras without a built-in IR-cut filter
• Astronomik UHC – better suited for emission nebula photography under heavy light pollution
• Astronomik UHC-E – suitable for emission nebula and comet photography under moderate light pollution
• CMOS and CCD: good, requires an additional IR-block filter
• DSLR (original): good, shifted color balance but increased contrast
• DSLR (astro-modified): very good, nearly perfect color balance
• DSLR (MC-modified): good, requires an additional IR-block filter
The XT version is specifically developed for wide-angle astrophotography. Its extremely thin substrate (0.3 mm or 0.5 mm) significantly reduces star distortion in the image corners, ensuring sharp star rendering across the entire field.
• 92% transmission at 486 nm (H-beta)
• 92% transmission at 496 nm (OIII)
• 92% transmission at 501 nm (OIII)
• 97% transmission at 656 nm (H-alpha)
• transmission range: 450–540 nm and above 650 nm
• glass thickness: 1 mm (except OWB Type 3 and XT filters)
• finely polished optical glass free of stress and inclusions
• extremely scratch-resistant coating
• fully resistant to humidity and aging effects
• Astronomik MFR coating
• parfocal with other Astronomik filters
• diffraction-limited design
• optimized transmission ranges
• supplied in a durable, high-quality filter box
All Astronomik filters are parfocal and diffraction-limited, ensuring that the optical performance of your system remains uncompromised. Each filter undergoes strict quality control before shipment.
