I designed this star system banner after using
the spherize tool in an online tutorial
The sun was made by making a flat texture use the
clouds filter and emboss filters. Then the spherize
filter was added and the outer edges were removed.
To add the glow I used the feather tool
planet were made in a similar way but the base
cloud effect used a heavier emboss and a cloud
flit with a decreased transparance was add to act
as clouds. As I had so many planet
to make I made a macro to created the effects.
The star background was made by using the noise
