my first post on the forum
a little collaboration to yours
on my images I use a litte software called Universe to create simple starfields
the link is the following
http://www.diardsoftware.com/and it's very very simple to use. you can create nebula, planets, galaxies, etc
but only the starfield looks great.
it's shareware, but the trial version allows you to make the starfields. and it doesn't expires
good you
