The spacing of the gobo and the lens may be varied to alter the size and focus of the image. A gobo in a gobo holder, which goes in a stage lighting instrument. The discolored portion is oxidation of the stainless steel caused by the high temperature of the lamp, but the gobo is still usable.he spacing of the gobo and the lens may be varied to alter the size and focus of the image.
