Well the smallest print I make is 11x14 and commonly do 16x20 and 20x24 with plans in the near future to do mural printing up to 50x whatever. So the more magnification you imply on the optical path, the more accuracy of alignment is required of your planes. So when I first asked this question, it was to basically say I wanted to cut to the chase and find out what is out there in terms of monorail view camera like adjustments of these planes on an enlarger.
