A flat field mask generates a white area with consistent brightness. To use, simply place the mask over the front of your telescope and take a photograph of the illuminated surface. This flat field image helps reveal the exact brightness pattern of your optical system, making it possible to correct brightness gradients in your astrophotography during image processing. For best results, use the mask under the same conditions and with the same optical setup as your actual images. The mask is built for portability and can be powered for use in the field.
