Peter,

OK...I've done better than that.

This is a link to a mouse-over of the blue versus H-alpha channel data, complete with spelling errors

As you will see H-alpha (a very deep, but visible red which DSLR's are quite insenstive to) dominates, with many features simply not emitting in blue at all.

Cheers

Thanks for that Peter,
I can see that the blue is no where near as strong as the red.
It would be interesting to see a different processing with
equal RGB colour graphs using curves in Photoshop -
in other words artifically balanced.
