Astronomik Filters SC CLS CCD filter (43796)

The Astronomik CLS-CCD filter is a high-performance tool designed for astrophotography under light-polluted skies, particularly for DSLR cameras that have been modified for astronomical use. It enhances the contrast between deep-sky objects and the background by blocking artificial light sources, such as sodium- and mercury-vapor lamps, while allowing important emission lines like H-alpha, H-beta, and OIII to pass through.

Description
The Astronomik CLS-CCD filter is a high-performance tool designed for astrophotography under light-polluted skies, particularly for DSLR cameras that have been modified for astronomical use. It enhances the contrast between deep-sky objects and the background by blocking artificial light sources, such as sodium- and mercury-vapor lamps, while allowing important emission lines like H-alpha, H-beta, and OIII to pass through. Its wider transmission curve compared to UHC filters ensures that stars are less dimmed, making it an excellent choice for capturing nebulae, galaxies, and star clusters.
 
Key Features
  • Enhanced Contrast: Blocks unwanted light while transmitting useful wavelengths, improving visibility of celestial objects.
  • Wider Transmission Curve: Allows more light to pass through compared to UHC filters, ensuring brighter stars and better image quality.
  • IR Blocking Layer: Enables use with DSLR cameras and webcams without integrated IR-block filters.
  • Halo-Free Design: Redesigned since 2008 to eliminate halos and reflections for sharper imaging results.
  • Versatile Applications: Suitable for DSLR-, CCD-, and black-and-white film photography, as well as visual observation of deep-sky objects.
 
Specifications
  • Frame Type: SC thread.
  • Coating: Multiple layers for durability and performance.
  • Compatibility: Designed for telescopes or photo lenses with apertures of f/3 and above.
  • 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 ideal for astrophotographers working in urban or suburban environments with significant light pollution. It provides almost 100% transmission of critical wavelengths while effectively blocking artificial light sources, ensuring detailed imaging of deep-sky objects without compromising optical performance.
