For star reduction I use select/colour range with about around 50-120 (it depends on the star field, so just try a bunch of different settings). Then I use select/ modify/ expand (1-2 pixels). Then modify again and then select feather 2 pixels. Now finally I use the minimum filter at 1 pixel. If necessary do this via a mask and use the opacity function to alter the effect of the filter.
The data is primarilty the Ha data which I blended with the R filter data and then used that same Ha data again as a luminance layer. For blending some where between 35% and 55% is fine. For Luminance I use somewhere around 55%-85%, just depending on how the blend looks. Everything is trial and error.
Hope this has been helpful.
