3x3 the image alignment is not as critical and is therefore OK but 
when I blow the same image up the alignment error is magnified and 
messes up the image?>

Ray Zone responds:

That is correct, Alex.  When the image is enlarged the blue and red 
"fringing" is increased as well.  The importance of the color values 
and their matching with the red and blue of the lenses also becomes 
more critical.  The same factor of enlargement also pertains to 
differences perceivable in a hand viewer and projection of stereo 
slides.  The larger the stereo image the less "forgiveness" there 
will be in the display form.
