1. An optical sighting device comprising:
a body with a first end and a second end and having a center axis;
an objective lens system disposed within the body;
an eyepiece lens disposed within the body;
an erector lens system disposed within the body; the objective lens system, eyepiece lens, and erector lens system forming an optical system having a first focal plane and a second focal plane, the first focal plane proximate the objective lens system and the second focal plane proximate the eyepiece lens;
a first reticle at the first focal plane;
a second reticle at the second focal plane, wherein the second reticle is a wire reticle;
the first reticle including at least one first marking;
the second reticle having at least one target dot illuminated by an LED, the target dot comprising an optic fiber having a first end and a second end, the first end including a light collector and the second end including an angled cut wherein the light from the LED passes through the optic fiber and reflects off of the angled cut; and
wherein the at least one first marking and the at least one target dot second marking provide complementary markings creating the appearance of a single reticle when viewed along the center axis.
