1. A method of operating optical systems, the method comprising: forming a stitched image of a field of regard using a first optical device, wherein the stitched image of the field of regard comprises a plurality of sub-images associated with a first field of view; designating an image of the first field of view of the first optical device as a target field of view located at a target location in the stitched image; receiving an image of a second field of view from a second optical device; determining a location of the image of the second field of view in the stitched image; defining a directional indicator that indicates a direction from the second field of view to the target field of view; communicating the directional indicator to the second optical device; and progressively displaying, in real time, on a display of the first optical device, the second field of view within the stitched image as the second optical device is moved according to the directional indicator.
