An apparatus for aiming a device such as a gun or a camera at a target without holding the device near the user's face. The apparatus has two sections: a viewer and an irradiator. The irradiator is rigidly attached to the device to be aimed, and projects towards the viewer an indication of the direction in which the device is aimed. The viewer includes an eyeport, through which the user observes the target, and a mechanism for projecting on the eyeport an indication of the deviation from the target of the aim of the device to be aimed. Preferably, the irradiator includes two light sources collinear with the aiming axis of the device to be aimed, and the viewer mechanism is based on planar optics.
