ABSTRACT:
A optical spotting scope in combination with an optical alignment viewer which includes a spotting scope body; a optical spotting scope lens system mounted within the spotting scope body to provide an optical axis therethrough and to further provide high power magnification of distant images within the field of view of the spotting scope lens system; a view finder body rigidly joined to the spotting scope body; and a optical viewer lens system selected, mounted and arranged within the view finder body to provide an optical axis therethrough in substantial parallel alignment with the optical axis of the spotting scope lens system so that the field of view of the viewer lens system coincides with and includes the field of view of the spotting scope lens system, the viewer lens system being substantially lower power magnification than the spotting scope lens system; whereby a distant image visible centrally within the field of view of the viewer lens system, will fall within the field of view of the spotting scope lens system.
