The DayStar Quark Magnesium I filter (DSZMG) isolates the magnesium absorption line for a unique photospheric solar view — offering a different perspective on solar surface structure than standard H-Alpha or white light filters. A specialty filter for advanced solar observers building a multi-wavelength solar imaging setup.
