I haven't used it for that, but if you wanted to use it on the stars just skip my StarXterminator steps and play with the BX settings.
Depending on the nature of your star bloat you may have more luck with other methods though.
Create a starless layer, then put the original (with stars) layer on top of it (in Photoshop, or your program of choice), set the blend mode of this star layer to screen, then create a curves adjustment layer and pull down hard on the curve. Convert this to a clipping mask. Then create a brightness/contrast layer, reduce brightness significantly (how much will vary by image), and convert to clipping mask.
You should now have significantly smaller stars. Play with the intensity of the two clipping masks to taste. This technique also works well for blending in RGB stars to narrowband images.
