Just put in your FL (1200mm) and your aperture (150mm) ignore everything else and hit generate. It generates a file that not all software can read. If you can't open it, download a copy of GIMP (free) and that can open the file. Hope that gets you on the way.

so after you enter the scopes details, the width would you just put the width of a piece of paper that you are printing the mask onto? this looks very good for a DIY mask and i have not used one yet, might print one off tomorrow. how do you guys normally attatch the print to the end of your scope?
