You can get PS plugins that try to reduce noise however it is better if the stacked image is low noise to begin with. I have the noise ninja PS plugin but there are others like topaz and neat image.
Here is your image with a quick noise ninja treatment.

Thanks. Yours is much nicer than mine
When you talking about sub, do you mean "light" in dss?
Before I DSS, I use bridge camera raw to reduce the noise from raw file. Should I do this way? many thanks.
