US Patent 11181606 Pointing system for manual telescope

An optical device such as a telescope may be oriented to view a subject. In one embodiment, an image capture device may be coupled to the optical device, and used to generate image data of a reference subject. The image data may be used to ascertain a first orientation of the optical device. A second orientation of the optical device, at which the subject is viewable using the optical device, may be ascertained. A rotation of the optical device needed to reorient the optical device from the first orientation to the second orientation may be calculated. Instructions may be outputted to the user, indicating how the user can apply the rotation to the optical device.
