Peter, Dave, list,

I just googled and found a lot of info on theory and construction (I 
typed in apodizing mask and hit search).  I always thought a apodizing 
mask was that gizmo with two or three holes in the mask.  It ain't! 
It's window screen!  The theory and practice are neat!

Chuck in hazy N. Fl (who wants to make the multi-hole gizmo for focusing 
perfection)
