What is "afocal photography"?
Afocal photography is a technique where a camera is used to take pictures through another optical device, such as a telescope or binoculars, without modifying the device's lens settings. In this method, the camera is simply aligned with the device to capture images as seen through it. This approach is often used to photograph distant subjects, such as astronomical objects or wildlife, by leveraging the optical power of the other device to achieve greater magnification and detail.
