An idea of mine which I have not been able to put into practice yet but
which might be usefull for this sort of thing is to have a combined stereo
viewer/binocular. The eye pieces would be contained in a rectangular
housing which could take a slide viewed by the eyepieces together with the
images from the objectives to enable the views to be directly compared.
