1. A method of generating a display for viewing a subject in a view through an eyepiece of a microscope, comprising:
determining a first pose of a viewing plane viewed through the eyepiece relative to the subject;
acquiring a first image of the subject at the viewing plane at the first pose at a first time as viewed through the eyepiece relative to the subject;
storing the first image;
displaying the first image in the view plane superimposed on a live image of the subject at a second time as viewed through the eyepiece relative to the subject;
determining whether a change in position of the live image relative to the first image has occurred; and
outputting a determination of the evaluation of whether a change in pose has occurred including superimposing a graphical representation indicating an amount of movement that has occurred between the first time and the second time.
