Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
When looking through a high-power scope you identify parallax by adjusting your gaze slightly. If the reticle changes position on the target when you shift your gaze, your parallax is not properly compensated for at that range.The reticle appears to move in relation to the target image because the focal planes are not coincident, making it appear to be a 3D image.hen the angle at which you are viewing the image through the eyepiece changes, the reticle position relative to the target image changes. In this illustration, the focal plane for the target image and the reticle are the same, so no parallax adjustment is necessary.
