Boy, wouldn't that be nice?  Mine goes much smaller, too.  But it 
probably won't work.

Smaller apertures give sharper images only up to a point, then 
diffraction effects spoil things. I think F16 and F22 are about it 
for useful apertures.  I have a Bercovitz spreadsheet somewhere that 
calculate this, but I am on my way to a birthday party.  MINE!
