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.

This dual band filter is designed to drastically reduce the effect of light pollution, it isolates the nebulae´s emissions into H-Alpha (red) and OIII (green-blue) and blocks light pollution.
- Transmits the main nebula lines at 656.3 nm and 500.7 nm with 3 nm bandpass
- Blocks light pollution and skyglow
- Designed mainly for astrophotography
- Especially suited for color cameras
- Ideal for urban areas with extreme light pollution
- Incorporates UV/IR cut filter
- Multi layers anti reflection coating
- Ultra thin filter cell maximises compatibility with filter wheels
