: If it does, it implies your stars are simply too small.  Without
: antialiasing you only see something because some stars are hit by accident.
: Antialiasing will take more samples, so a star will not be hit for every

: result, you create an effect you do not desire...

: I would also suggest to follow the other poster's suggestions and increase
: the size of the stars.  You can i.e. do this by simply scaling the
: background up.
