At longer wavelengths, atmospheric turbulence ('seeing') has a significantly reduced impact on image sharpness. This results in much sharper images of dark structures on Mars, Jupiter, the Moon, and even the Sun. These details can be incorporated as a fourth color channel in RGB imaging. This filter is an excellent tool for any CCD camera owner looking to improve imaging under poor seeing conditions.

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).
