I like the result there Phil but as you say you can get a more impactful colour going.
What you've got there is your classic Ha as luminance red washout that turns the reds a bit salmon coloured.
Here is a detailed post of how I do Ha (for what its worth) its really one of two approaches but in the end they really do much the same thing.
My approach is Ha in red, Ha in blue (10%) in lighten layers and Ha in luminance using luminosity mode.
This essentially is the same as doing a blend of Ha and luminance and then using that as the luminance and combining Ha and red and using that as the red.
My way you can save it as a psd file with all the various layers and come back to it later if you don't like it.
You also control the red using curves. This is similar to Tony Hallas and Russell Croman tutorials on the subject.
I sometimes use a few other tweaks but not that important, this is the guts of it:

I got my Pentax 67 lens adapter today for my FLI proline and pdf focuser so looking to give you some competition for Malins in the widefield category hehehe.

Hey, you've got plenty of awards to share around!
By the way I missed that 300mm EDIF, he sold it someone just before me. Its OK I can't afford it at the moment anyway.
