Digiscoping

Digiscoping is a type of afocal photography, using a digital camera to record distant images through the eyepiece of an optical telescope.

It commonly involves either a digital single-lens reflex camera with lens attached or, more often, a fixed-lens point and shoot digital camera, mounted to obtain photos through the eyepiece of a birdwatcher's spotting scope. The term has also been associated with the use of a digital camera and spotting scope equipped for prime focus photography.DphotoNews's blog - Nikon introduces the Digiscoping System - Fieldscope Digital SLR Camera Attachment FSA-L1

Origins The portmanteau neologism digiscoping (= digital camera + telescope) was coined in 1999 by French birdwatcher Alain Fossé. Less notable neologisms for this activity are digiscope birding, digiscopy birding, digi-birding, digibinning (using digital camera with binoculars), and phonescopingOrnithomedia - Pratique - Equipement, A new step in ornithology Digital (using a digital camera phone with a spotting scope or binoculars).

The origin of 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 Fossé, coined the name digiscoping to describe the technique.Digiscoping: What is it? Poh is sometimes credited with "inventing" the technique,Cornell Lab of Ornithology, Birding Basics, Digiscoping 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) has been used for nearly 100 yearsNVMUG eNews 4/21/2001 Bill Amos’ Digital Photography Presentation and Warren Walker's Photo Editing - "in the 1930s Bill used afocal photography when taking pictures through a microscope" and digital camera afocal photography was already being employed in the amateur astronomical community.Michael A.
