The ongoing "CMOS-revolution" in astronomical imaging, with increasingly sensitive cameras and decreasing pixel sizes, forces us to bring our time-proven narrowband filters to a new technical level. Also in the future our filters will remain to be the reference-standard – with real measurement curves shown, covering the entire spectral sensitivity range of modern CMOS cameras, against which cheaper filter copies will have to measure themselves.
