I have been trying to learn all there is to know about AP, after my stunning (
) image of Omega. I am doing the processing in Star Tools 1.4 and always suddenly come across this "mask". It tells me I either have not got enough pixels, or I have too many. Then the screen goes green and it tells me to "Invert" then "shrink" and then...wait for it..."Grow"! What is a mask supposed to do? Any simple explanations????
