Projection Photography
Here the optical image that the telescope's optics deliver is further magnified
by the use of a magnifying lens. In most cases an eyepiece is used for
this purpose. (therefore the name) What follows is a collection of pictures
of the planet jupiter during the impact of the comet in 1994. In this case
the film was replaced with a video camera as a detector.
