boresight

Boresight refers to the precise alignment between a device's aiming mechanism—such as a camera, telescope, or weapon sight—and its actual line of sight or target path. When properly boresighted, the device's line of sight matches the intended target direction, ensuring accurate aiming and targeting. The process involves calibrating and adjusting the device so that its visual indicator or crosshairs correspond exactly with where the device is pointing relative to the target. In essence, boresighting ensures that what you see through the device aligns perfectly with where it is aimed, improving accuracy and effectiveness.
