  • Blocks mercury and sodium-vapor spectral lines while permitting the largest section of visible light and H-alpha emissions to get through, thus doing away with that annoying orange glare brought about by heavy light pollution in urban areas
  • The Astronomik CLS-CCD Filter displays more stars and nebula features
  • Best suited for telescopes or photo lenses of all apertures with a focal ratio of f/3 and above for DSLR, CCD, and black & white film photography, and for deep sky viewing
  • Constructed in a 2" round, mounted format
  • Allows nearly 100% transmission in the visual and H-alpha area of the spectrum, 450 nm to 530 nm
  • All Astronomik filters contain multi-layer coatings for protection against blemishes from scratching, aging and high humidity
  • German-made for exceptional optical quality!
