This filter is specifically designed for astrophotography using the calcium lines in the solar spectrum. It comes with AstroSolar photo film (ND=3.8) in a 200x290mm format for pre-filtering sunlight. The filter isolates the two calcium lines at 393nm and 396nm, producing a deep blue image. This enables observation of a region of the Sun located between the photosphere (visible in white light) and the chromosphere (visible in H-alpha light).
