1. An optical apparatus, comprising: an optical lens system configured to relay an image of an anatomical target to an image acquisition assembly via an optical imaging path provided by the optical lens system, the optical lens system including: an objective lens configured to be located near the anatomical target; and an alignment assembly configured to be user-positionable at least partially in the optical imaging path; wherein an image presented via the optical imaging path includes a first field of view to provide an image of an anatomical landmark when the alignment assembly is included at least partially in the optical imaging path, and a second field of view to provide the image of the anatomical target when the alignment assembly is substantially excluded from the optical imaging path; wherein a focusing target is produced by the optical lens system and is presented to the image acquisition assembly without use of a prismatic focusing aid; wherein the image acquisition assembly comprises a digital camera configured to automatically obtain a focus on a desired portion of the anatomical target using a reflection of the focusing target relayed to the image acquisition assembly via the optical lens system without using a prismatic focusing aid; and wherein, the optical apparatus is configured to automatically perform at least one of repositioning the alignment assembly, enabling a projection of the focusing target onto the anatomical target for at least a specified duration during which the digital camera obtains focus, or disabling projection of the focusing target after the digital camera obtains focus.
