Function
The most common form of digiscoping is called afocal projection. This is done by holding or mounting a camera over a telescope's eyepiece.
Significance
Digiscoping is not a new practice. The first form of digiscoping, astrophotography, was developed by astronomers.
Uses
Although digiscoping is closely associated with astronomy, another use is for bird watching. This is referred to as digiscope birding. Other uses include photographing plants, insects or wild animals.
Benefits
Digiscoping is cost-effective compared to purchasing telephoto lenses. The technique produces high magnifications, images already in focus and photos that can be easily edited because of the digital process.
Potential
A recent type of digiscoping is phonescoping or mobiscoping, which is the practice of using a wireless camera phone to digiscope objects instead of a digital camera.
