So I figured out with some help from another member friend on this site how to download Starnett into Pixinsight. It is a process tool now. When I open a non linear image and open the StarNet tool a little box opens that gives me the choice of 128, 64,32,16, or 8. Is this the file size it will generate? It also has a small box to check off to generate a star mask. I checked the box and drag the triangle onto my image, after a minute it produces a star mask.
Is this the proper way to generate a starless image? I thought it was supposed to do it automatically.
I ended up subtracting the star mask from the image using Pixel Math, and it made a starless image. Am I doing this correctly?
Thanks for anyone's help.
