Re: [ATM] Couder Masks and Zone Testing

I don't know how you can make a Couder mask with software.   I always used
black paper or cardboard and an X-acto knife.

Note that it is best when testing to isolate the mask from the mirror.  
That way you can adjust the mask position without disturbing the distance
from the mirror to the knife edge.
