With POV-Ray 3,7 beta37a and 3.6.2 (Win64):
camera {
panoramic
location <0, 0, 0>
look_at <0, 0, 1>
angle 360
}
Horizontally and vertically!
Vertically may be okay,
In POV-Ray Reference:
"It uses a type of cylindrical projection to be able to use viewing
angles larger than 180 degrees with a tolerable lateral-stretching
distortion. The angle keyword is used to determine the viewing angle."
Did I missed something or
is this really a bug which I should add to Flyspray?
????

For a sky sphere you'll want the "spherical" camera.

Apparently this is a documentation error - either that, or the panoramic
camera has never worked the way it was intended to; POV-Ray 3.6.2 shows
the same behavior.

Thanks for clearing this!
Your right: The spherical camera works correkt for skyspheres!
