Abstract: A viewing device captures one or more images from a spotting scope. A communication device transmits the images to one or more remote display devices. A self-aligning mount allows the viewing device to be automatically aligned with an optical pathway of the spotting scope as it is attached thereto. An adjustment ring allows focusing adjustments to be made to the spotting scope, even after the viewing device is attached. With the viewing device, a user need not physically move to peer through the spotting scope, since images from the spotting scope may be remotely viewed at one or more remote display devices. In addition to spotting scopes, the viewing device may be used with other optical devices, such as binoculars, telescopes, rifle scopes, microscopes, and other optics.
