digiscoping

Digiscoping is the practice of capturing photographs or videos through an optical instrument, typically a spotting scope or telescope, by mounting a camera or smartphone to the optical path. The aim is to combine the magnification of the scope with the imaging sensor of the camera to document distant subjects with greater detail than could be achieved with a standard lens alone.

There are two main methods. In the afocal method, the camera remains with its own lens and is positioned to view through the eyepiece of the scope, often using a dedicated adapter or cradle. The scope acts as a finder and magnifier, while the camera records through the eyepiece. In the projection method, the eyepiece is replaced or an adapter is used to project the telescope’s image directly onto the camera sensor, typically requiring a T-mount or similar interface to connect the camera body or a dedicated imaging device.

Equipment commonly used includes a stable tripod or support, a suitable spotting scope or telescope, and adapters tailored to the camera type (DSLR, mirrorless, compact, or smartphone). Image quality depends on the instrument’s optics, atmospheric conditions, and careful alignment and focusing; some subjects may require manual exposure control and post-processing.

Applications span wildlife and bird photography, nature observation, and field astronomy, where distant or small subjects benefit from high magnification. Digiscoping has grown with affordable smartphone adapters and lightweight imaging rigs, expanding accessibility for hobbyists and researchers alike.
