Riflescope with attachable aiming corrector and method for using same

A riflescope, comprising:

• a. a housing, said housing having a front end, a rear end and a middle section,
• b. an objective lens that forms a first image of a target, said objective lens being mounted inside said housing at a front end of said housing, said objective lens having an optical axis and a focal plane;
• c. an image-erecting means for converting said first image of the target into an upright second image of the target, said image-erecting means being mounted inside said housing after said objective lens;
• d. an eyepiece lens that converts said second image of the target into a virtual image of the target viewable by a shooter, said eyepiece lens being mounted after said image-erecting means, said eyepiece lens being mounted inside said housing at a rear end of said housing, said eyepiece lens having a focal plane;
• e. a reticle that designates a point of aim, said reticle being mounted either at the focal plane of said objective lens or at the focal plane of said eyepiece lens, an image being superimposed on the virtual image of the target;
• f. a collection of wedge prisms, each said wedge prism in said collection including a deviation power of a certain amount, each said wedge prism in said collection having a deviation axis which is a hypothetical axis that points from an apex of said wedge prism towards a base of said wedge prism;
• g. a fastener means for attaching at least one wedge prism of the collection of wedge prisms to a front end of said housing such that
• i. the wedge prisms of the collection are positioned before said objective lens;
• ii. light rays that enter said objective lens pass through the wedge prisms of the collection;
• iii. the deviation axes of the collection of wedge prisms are orientable to a plurality of specified directions perpendicular to the optical axis of the objective lens;
• and
• iv. the wedge prisms of the collection are fixedly attached to said housing
• whereby the point of aim denotes the riflescope corrected to correspond to a point of impact of a rifle associated with the riflescope.
