Colour CCD cameras such as the Skyris colour planetary cameras are very sensitive across the visual spectrum, as well as in infrared. Some telescopes may correct for chromatic aberration, but are not designed to correct for IR light, which can often look defocused in astroimages. Blocking infrared (IR) light provides the greatest colour balance and sharpness in your astroimages. This filter blocks IR while passing more than 94% of the entire visual spectrum, maintaining colour fidelity.
