Altair Quad-Band 2" Filter for OSC CMOS, CCD and Modified or Unmodded DSLR cameras.

This is the new QuadBand V2 Coating technology which includes:

  • Anti-Halo coating on both surfaces to reduce reflection artefacts from reducers and camera lenses.
  • Increased blocking of UV, IR and unwanted visual range wavelengths. UV OD7 (T0.00001%) Visual OD5 (T0.001%) and IR OD4 (T0.01%) for the ultimate in skyglow blocking.
  • Higher transmission % of desired wavelengths Ttop 95% (Average 5% higher transmission of desired wavelengths).
  • Ha and Oiii wavelengths at 35nm FWHM for with less tail-off to reduce unwanted light pollution.
