Problem:
When I render my scene with a Galaxy Plugin object in the background (and nothing
else), The background of my image is rendered as mostly transparent. I want the Black
to show up so that the stars etc. 
can be easily seen. Is there any way to turn this feature off? I have tried starting
pov with the -UA switch to no avail. I'm just about ready to pull my hair out!!!! Any
help appreciated.

The galaxy backgrounds (stars and nebulae) are created using the sky_sphere,
which will be transparent if you render with the alpha channel enabled.
However, if you are using the -UA switch this should not be a problem.  If
you are finding the stars are very faint and transparent-looking, try
rendering without anti-aliasing (or a higher threshold value).
