That worked brilliantly from the point of view of tiny Takahashi stars and sharper H-alpha nebulosity, but sadly it did lose a lot of the blue nebulosity.
If you think you can stand it, you could aim for a halfway house. There are many ways to do this.
In Photoshop for example, you can set the H-alpha as a luminance layer, and then adjust the transparency of the luminance layer to produce a best compromise where you've still got plenty of blue but the stars are still small.
Hope I'm not being obnoxious.
Best,
Mike
