That has undoubtedly contributed to the wholesale ignorance of your idea!I tried your method and think it's useful. The point is, I believe, that defocusing relaxes one's attention from anything interesting in the view to be looked at, and makes the sharp field stops stand out better, and thus easier to bring into alignment. A pitfall exists however--defocusing brings the image to some apparent point other than infinity, and thus the eyes potentially slightly crossed rather than parallel, so one must be sure to keep the eyes relaxed and gaze at infinity, and not "try" to examine the out of focus image.
