SV227 2" SII 5nm Filter Narrowband Filter sv205 camera stored and transferred with fewerThe SVBONY SV227 SII filter is a 2 narrowband astrophotography filter with a 5 nm bandwidth, designed to isolate the sulphur II emission line at 672. 4 nm. It is intended for deep sky imaging of emission nebulae, where strong suppression of light pollution and background sky glow is required. 5 nm Narrowband Precision With a narrow 5 nm passband, the SV227 SII filter provides high contrast by isolating the sulphur II emission wavelength while
