The Astronomik SII 6nm M49 filter is a high-performance narrowband filter designed for astrophotography, particularly for imaging emission nebulae and faint deep-sky objects. It isolates the ionized sulfur (SII) spectral line at 672 nm, providing exceptional contrast by blocking unwanted light from UV to IR. With its narrow 6nm full width at half maximum (FWHM), this filter is ideal for use in light-polluted areas or when imaging in star-dense regions of the Milky Way.
