SVBONY SV160 2 SII Filter 7nm Narrow-Band for CCDs 

  • SVBONY Sulfur II 7nm Extra Narrowband Filter transmits a 7nm bandwidth of light that is centered at 672nm and drastically reduces other transmissions; including wavelengths of light that are responsible for light pollution
      • Quality lens material;The SVBONY 2inch filters are made with Schott glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength or CWL
          • Rugged metal frame;The SVBONY filter cell is made of lightweight; strong metal and is CNC machined; sand-blasted; black anodized; and then laser engraved
              • Standard 2-inch thread size; Metal filter cell threads directly into the 2- inch barrel of your telescope eyepiece
                  • SVBONY 2inch SII-CCD filter is for the astrophotography; lets you increase the contrast when photographing deep sky objects; It stands out better against the night sky background; letting you see detail that was not apparent before
                      • The Sulfur II 7nm Extra Narrowband Filter transmits a 7nm bandwidth of light that is centered at 672nm and drastically reduces other transmissions, including wavelengths of light that are responsible for light pollution (both artificial and natural). Like all SVBONY filters that are designated as “CCD”, this SII filter also blocks infrared wavelengths from 700nm to 1100nm so you don t need a separate IR-Cut filter

                      • Thin metal cells have a clear aperture of 45mm for 2inch filters,each filter comes with a plastic case with high pressure EVA case lining

                      • Made with Schoot glass
