A parabolic mirror (as is used in a mirror-type telescope) collects the
light from distant objects (like the moon, planets, etc.) and projects a
"real" image of those objects at its focal point (where the eyepiece lens
is positioned).  If you were to put a piece of paper at the focal point you
would "see" the image on the paper.  This is different from a "virtual"
image that is ssen when you see yourself in the mirror.

Does POV-ray have the funtionality to simulate the "projected" image from a
parabolic mirror?
