Astronomik Filters CLS XL Clip Canon EOS R (64981)

The Astronomik CLS filter is an affordable and versatile tool designed for visual observation, black-and-white photography, and CCD imaging of deep-sky objects such as nebulae, galaxies, and star clusters. It is highly effective in reducing light pollution by blocking spectral lines from mercury and sodium-vapor lamps while allowing most visible light and H-alpha emissions to pass through. This makes it an excellent choice for enhancing contrast and image quality under light-polluted skies.

This makes it an excellent choice for enhancing contrast and image quality under light-polluted skies.
 
Key Features
  • Light Pollution Reduction: Blocks artificial light sources like mercury and sodium-vapor lamps while transmitting important astronomical emission lines.
  • Optimized for Aperture Ratios: Best suited for telescopes with aperture ratios between 1:3 and 1:15, ensuring minimal transmission loss or chromatic distortion.
  • Durable Design: Resistant to high humidity, scratches, and aging effects, with a glass thickness of 1mm.
  • High Transmission Rates:
    • 92% at 486nm (H-beta)
    • 92% at 496nm (OIII)
    • 92% at 501nm (OIII)
    • 97% at 656nm (H-alpha)
 
Specifications
  • Mount Material: Aluminum.
  • Frame Type: Clip-Filters.
  • Series: CLS.
  • Type of Build: Broadband Filters.
  • Compatibility: Suitable for Canon EOS cameras.
  • Applications:
    • Visually useful: No.
    • Useful for photographs: Yes.
