A flat field mask produces a white area with uniform brightness. To use it, place the mask on your telescope optics and photograph the illuminated surface. This flat field image reveals the precise brightness distribution of your optical system and helps you correct any brightness gradients in your astrophotographs during image processing. For the best results, use the mask under the same conditions and with the same optical setup as your main images. The mask is designed for portable use and can be easily powered in the field.
