Filters for images use specialized precision coatings to add a layer of false color to a black and white, monochrome image. These colored frames are then stacked to create full-color images. Here you'll find standard LRGB filters, narrowband filters such as H-Alpha, Oxygen III and Sulfer II, UBVRI filters and specialty filters designed specifically for imaging with CCD or CMOS cameras as well as filters designed to enhance astronomical objects for DSLR cameras.
