thanks Bob. The technique has it's problems, worst of which that the (bigger) stars in RGB cover up some of the surrounding nebula and you end up with regions around the (smaller) Ha stars where the colour information is that of the star, but the luminance is that of the nebula - leads to odd coloured halos around the stars. I tried a variety of methods to suppress this effect, with fair success, but not total.

thanks Greg - yep, I like the drama in this object as well
