Abstract
An improved reticle for optical instruments such as telescopic sights, riflescopes and surveying telescopes, provides a primary indicator at the focal plane of the instrument and a secondary indicator spaced, axially, apart from, and viewable with, the primary indicator. When an operator's eye is properly centered on the optical axis of the instrument, the indicators provide visual feedback to the operator of such proper alignment. When an operator's eye is laterally displaced from the optical axis, the indicators provide visual feedback indicative of improper positioning of the eye. Thus, an operator may readily, and intuitively, make the necessary adjustments to the relationship of the eye to the optical axis to correct for misalignment without the need for cumbersome mechanical adjustments and special mechanisms.
