ABSTRACT:
A sight includes a housing with first and second openings, and includes an optics section that is disposed within the housing, that has image erecting optics and eyepiece optics, and that optically influences radiation received through the first opening from a scene, so as to deliver through the second opening a viewable image that is a function of the radiation. An adjusting section facilitates adjustment of the position of the image erecting optics and the eyepiece optics within the housing.
