    • A sighting device for use, for example, with a shotgun, the device employing a reticle of fluorescent acrylic polymer disposed out of the field of view. The image of the reticle is projected into the field of view by a preferably dichroic partial reflector. Windage and elevation adjustments are included for moving the reticle to zero in the device on the target in the field of view. The image of the reticle is collimated so as to appear in focus with the target to the eye of the observer.
