If it looks like that in Pov, that is probably y how it would look IF you
were using an identical camera. You CAN fix this distortion (if it is
camera-based) by moving the camera further back, and then decreasing the
'angle' perameter of the camera. (I did a post on this in the
Advanced-users section, but nobody noticed) The sad bit is that you then
lose depth to your image.

Try a transparent cylynder (pigment {rgbt 1}), using 'hollow' and filled
with emmissive media, or a very small light source using 'cylindrical' and
'spot_light' passing through a cylinder that is transparent and 'hollow',
and filled with scattering media (interior{ior 1 media {scattering {...}}})

If you do a search in the Docs for media, you'll begin to get the idea.
