Astronomik CLS-CCD Light Pollution Filter - 50 mm Square




  • Eliminates the orange glare resulting from severe light pollution in metropolitan areas by allowing the largest portion of visible ligt and h-alpha emissions to pass through while blocking mercury and sodium-vapor emissions, common causes of light pollution
  • Presents extra nebulae features and additional stars
  • In addition to making an excellent filter for imaging, the Astronomik CLS CCD Light Pollution Filter also works well for observing deep sky objects with all aperture telescopes or with f/3 focal ratio and above photo lenses.
  • Presented in a 50 mm square format
  • Close to 100% of the visual and h-alpha portions of the spectrum, 450 nm to 530 nm, is allowed to be transmitted
  • Astronomik filters all have multi-layer coatings to protect against the negative effects of scratching, aging, and high humidity
  • German-designed for supreme quality optics!




More About the Astronomik 50 mm Square CLS-CCD Filter




DSLR Cameras have been remodeled for astronomical use, making them suitable for use with the CLS-CCD Filter in an extremely light-polluted environment. This filter highlights the contrast between the background and your selected object. It also has a wider transmission curve compared to UHC filters, transmitting more light to render stars that are less dimmed. The Astronomik CLS-CCD Filter has been optimized to simultaneously intercept as much spurious light as possible while providing the best performance for approved wavelengths.



A good filter for DSLR, CCD, and black & white film photography, along with deep sky observation. By blocking mercury and sodium-vapor lamps, and letting the largest section of visual and H-alpha emissions to pass, the CLS-CCD filter effectively cuts out the majority of surrounding light pollution, eliminating that irritating orange glow. This filter works best with lenses of all apertures with focal ratios of f/3 and above.



Alternative uses for the Astronomik CLS-CCD Light Pollution Filter include easier Double Star resolution, and emission line data color imaging in the Luminance channel. As with all Astronomik filters, the CLS-CCD is parfocal with all other filters made by Astronomik. It is highly resistant to scratching, aging, and high humidity, and has a thickness of only 1 mm. This filter is also diffraction limited so you won't experience any drop off in your telescope's optical performance. Like all Astronomik filters, the CLS-CCD comes with a high-quality, long-lasting plastic storage case.



Transmission Specifications:




  • 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)
  • Pass from 450 to 540 nm and beyond 650 nm
