Svbony SV220 7nm Dual-Band Nebula Filter SII & OIII

The SV220 SII & OIII  7nm is a Duo Band Filter. It is designed to be used in combination with the SV220 H-Alpha & OIII Duo Band Filter to provide a superior method for achieving the SHO (Hubble Pallet) narrow band colour balance with colour imaging cameras. The SII and OIII Filter provides the missing band data so that owners of colour cameras can achieve the SHO colour balance in their narrow band images. The Duo-band filter (SII+OIII) has a high transmission of over 85% at its center wavelength (500.7nm and 672nm). It can effectively improve the quality of the image by making the sky background of the image darker while maximizing contrast throughout the image and enhancing the contrast of your pictures, thus making it easier to display the details of the stars. In areas with very serious light pollution, this filter can also selectively filter light pollution.
