Target sight system including reflex sight having emitter array

A target sighting system for a firearm, comprising

• a reflex sight, including:
• an emitter array including a plurality of light emitters, each of the plurality of light emitters capable of being independently operated to produce light,
• a surface structured to reflect light from the emitter array to a user of the firearm, and
• a controller configured to individually control operation of each of the plurality of light emitters in the emitter array;
• and
• a mobile computing device wirelessly coupled with the reflex sight, the mobile computing device including a software application operating on the mobile computing device and configured to receive input from a user interacting with the computing device and, based on the input, to cause the computing device to send instructions to the controller via wireless communication to control operation of the emitter array,
• wherein the controller is configured to illuminate a first subset of the plurality of light emitters of the emitter array in a predefined reticle pattern, and the software application is operable to receive user interaction with the mobile computing device that causes the mobile computing device to instruct the controller via wireless communication to illuminate a second subset of the plurality of light emitters in the predefined reticle pattern, wherein the second subset is different from the first subset.
