C. TELESCOPES FOR PHOTOGRAPHY
Telescopes can be used for photography of any distant object, whether
on land, sea, or sky. Simple camera attachments are available to allow
you to shoot images right through the eyepiece (called digi-scoping or
afocal photography), paralleling the telescope (called Piggyback photography)
using the camera’s own lens, or through the telescope using the
telescope as a lens for the camera (called prime-focus photography). Also,
there is an astronomically-oriented technique called Stationary Photography,
which is used when a picture of the motion of the Earth under the sky
is desired. All that’s required for this is a camera, a platform
or tripod to put it on, and the ability to keep the shutter open for long
periods of time.
Each type of photography has its own use, depending on the amount of
magnification needed, and the width of field desired.
