Astronomik Filters CLS CCD 31mm filter, mounted (52922)

The Astronomik CLS-CCD filter is designed for astrophotography and observation under light-polluted skies, particularly for DSLR cameras that have been modified for astronomical use. It enhances contrast between deep-sky objects and the background by blocking artificial light sources like sodium- and mercury-vapor lamps while allowing important emission lines and visible light to pass through. Its wider transmission curve compared to UHC filters ensures more light passes, making stars appear less dimmed.

Description

The Astronomik CLS-CCD filter is designed for astrophotography and observation under light-polluted skies, particularly for DSLR cameras that have been modified for astronomical use. It enhances contrast between deep-sky objects and the background by blocking artificial light sources like sodium- and mercury-vapor lamps while allowing important emission lines and visible light to pass through. Its wider transmission curve compared to UHC filters ensures more light passes, making stars appear less dimmed. This filter is ideal for observing nebulae, galaxies, and star clusters with telescopes or photo lenses with apertures of f/3 and above.
 
Key Features
  • Light Pollution Reduction: Blocks artificial light sources and airglow while transmitting H-alpha, H-beta, and OIII emission lines.
  • Wider Transmission Curve: Allows more useful light to pass through, enhancing visibility of stars and deep-sky objects.
  • IR Blocking Layer: Enables use with DSLR cameras and webcams without integrated IR-block filters.
  • Durable Design: Resistant to scratches, humidity, and aging effects; maintains optical performance.
 
Specifications
  • Frame Type: Ring.
  • Filter Size: 31mm.
  • Series: CLS CCD.
  • Type of Build: Broadband Filters.
  • Applications:
    • Useful for photographs: Yes.
    • Anti-light pollution: Yes.
    • Suitable for galaxies, star clusters, planetary nebulae, supernova remnants, and hydrogen nebulae.
    • Visually useful: No.
This filter is an excellent choice for astrophotographers using DSLR or CCD cameras who want to capture high-quality images of deep-sky objects while mitigating the effects of urban light pollution. Its "Halo-Free" design ensures clear and sharp results even in challenging conditions.
