A sight attachable to a weapon and comprising an objective lens, an image display, and a digital reticle. The objective lens focuses infrared light received from a scene onto a thermal imager, which is comprised of a focal plane array that detects infrared radiation in the scene focused by the lens. The image display is in signal communication with the thermal imager and provides an image of the received infrared light from the scene. The image rendered by the display is visible to the user. The digital reticle is rendered on the display and provides an aim point of the weapon upon a target in the scene. The image of the scene and superimposed reticle are directly viewable by a user with the aim point of the weapon upon the target being maintained constant over a range of viewing angles that depart from a viewing angle perpendicular to the display.
