Photographic technique
Spotting scope
with a digital camera mounted afocally using an adapter.
Digiscoping waterfowl
Typical uncropped digiscope image; the
spotting scope
has 20x magnification. Camera focal length is 24 mm; distance to the subject is about 90 meters.
Digiscoping
is a
neologism
for
afocal photography
, using a (
digital
) camera to record distant images through the
eyepiece
of an
optical telescope
.
Digiscoping usually refers to using either a
digital single-lens reflex camera
with lens attached or, more often, a fixed lens
point and shoot
digital camera to obtain photos through the eyepiece of a
birdwatcher
's
spotting scope
.
[1]
The term has also been associated with the use of a digital camera and spotting scope equipped for
prime focus
photography.

Origins
[
edit
]
The portmanteau term "
digiscoping
" (= digital camera + telescoping) was coined in 1999 by French
birdwatcher
Alain Fosse
. Less notable neologisms for this activity are
digiscope birding
,
digiscopy birding
,
digi-birding
,
digibinning
(using digital camera with
binoculars
), and
phonescoping
[3]
(using a digital
camera phone
with a spotting scope or binoculars).
The origins of the activity called
Digiscoping
has been attributed to the photographic methods of
Laurence Poh
, a birdwatcher from the
Malaysian Nature Society
, who discovered in 1999 almost by accident that the new generation of
point and shoot
digital cameras could be held up to the eyepiece of a standard spotting scope and achieve surprisingly good results.

He spread his findings through birding
internet discussion forums
and one member, French birdwatcher Alain Fosse, coined the name "digiscoping" to describe the technique.
[4]
Laurence Poh is sometimes credited with "
inventing
" the technique
[5]
although his contribution may be more along the lines of popularizing the idea and refining the technology.
Using a camera with its lens attached at the eyepiece of optical devices such as microscopes or telescopes, creating an
afocal system
(technically called
afocal photography
or
afocal projection
) had been used for nearly 100 years
[6]
and digital camera afocal photography was already being employed in the amateur astronomical community.
[7]
This form of afocal photography became more common in general photography in the 21st century with the spread of point and shoot digital cameras
[8]
because of the ease of use of this type of setup.
[9]
Several companies sell couplers and other devices for mounting digital cameras afocally.
