The change of angular place of two fixed points relative to each other as seen by an observer, as a result of the motion of an observer.
The evident shift of an object against a background because a modification of observer position.
The position of witnessing of the astronomical device.
The apparent displacement, or huge difference of place, of an object, as seen from two different programs, or points of view.
The obvious difference in place of a body (since the sunshine, or a star) as seen from some point on the earth's surface, so that as seen from various other old-fashioned point, given that planet's center or even the sunshine.

In optics, an apparent shifting regarding the spider-lines in a telescope-reticle because the attention is moved ahead of the eyepiece: it is as a result of non-coincidence associated with threads using focal-plane of the object-glass.
