DayStar Interference Eliminator (T/C Mount) Style:C Mount The 8409 hand controller canPhotographers imaging in monochromatic light, such as Hydrogen Alpha, using an electronic sensor frequently encounter a wavy pattern of light and dark lines superimposed over their images. These lines are called interference fringes, interference patterns, or Newton's Rings. In long focal ratio applications, the nearly parallel light can internally reflect inside the image sensor or camera, causing an addition or subtraction of the light waves,
