Description: The SVBONY Sulful II Extra Narrowband Filter transmits a 5nm bandwidth of light that is centered at 672nm and drastically reduces other transmissions, including wavelengths of light that are responsible for light pollution. This SII filter blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter. Due to the narrow bandwidth and high transmission rate of this filter, you will experience a major boost to contrast. Please Note: This SII filter is NOT for use on the Sun.
