Claim:
1. A method for aiding aiming of a projectile device with respect to a target, the projectile device functionally coupled with a telescope having a primary sight alignment indicator carried in a reticle, an objective lens and an optical axis, said method consisting of: (a) disposing a sight aid comprising an illuminated supplementary sight alignment indicator, forward of the objective lens such that said supplementary sight alignment indicator is centrally located with respect to the optical axis and said supplementary sight alignment indicator is disposed at a distance from the primary sight alignment indicator, wherein said sight aid is configured to allow direct line of sight of the target along said optical axis; (b) pointing the telescope at the target; (c) centering an image of the target on said optical axis; and (d) centering a composite image of the primary sight alignment indicator and said supplementary sight alignment indicator to one another and the image of the target along said optical axis to produce an indication of deviation of said images of the axially-centered primary sight alignment indicator and axially-centered supplementary sight alignment indicator and said target image along the optical axis such that an action can be taken to remove such deviation to assure accurate alignment of the optical axis of the telescope with the target so as to perfect aim of the telescope with respect to the target.
