1. A direct, see-through optical system having a main optical axis extending from an ocular end to an objective end of the optical system, the main optical axis of the optical system structured to be fixedly aligned with a long axis of a shooting device, the see-through optical system comprising:

  • an electronic inclinometer structured to determine a cant of the shooting device relative to a vertical transverse axis of the main optical axis of the optical system; and

    an electronic indicator structured to provide an indicator signal to a user related to the determined cant, including;

    a first light indicator disposed adjacent a periphery of the optical system structured to be selectively illuminated to indicate a cant in a first direction; and

    a second light indicator disposed adjacent the perimeter of the optical system structured to be selectively illuminated to indicate a cant in a second direction, the first and second light indicators each located on opposite sides of the vertical transverse axis and along a horizontal axis of the optical system.
