A night vision sight is provided for use with a weapon, which includes an objective lens and a non-inverting image intensifier tube disposed along an optical axis, providing an intensified target image. The sight is focused by direct movement of the image intensifier tube relative to the fixed position of the objective lens. A reticle projector is disposed orthogonal to the optical axis and provides a collimated reticle image, the reticle image providing an aiming point for the weapon. The reticle image is superimposed over the target image, which are reflected into an eyepiece of the sight. The eyepiece has an axis between the optical axis and a sight line passing through a pre-existing sight provided with the weapon. Adjustment of the apparent position of the reticle to compensate for azimuth and elevation is accomplished by moving the reticle projector about crossed cylindrical bearings.
