Great stuff John. You should be suitably chuffed.
I'm also a newbie and in my few attempts to date I'm always mystified by how to present my images, colour-wise. I often go to NASA for ideas. I do know an un-modded DSLR has an IR cut filter that filters out a lot of the H-Alpha reds.
I'm also aware that PP is very subjective but I wondered how much more red I could tease out of your low res images and to that end I had a fiddle in CS6>Image>Adjustments>Selective Colour. In the RED channel I found that backing off the Cyan slider and slightly boosting the black slider there is quite a bit more red intensity available. I also had a fiddle with the neutrals sliders and the White Balance and Dehaze tools in Camera Raw.
Another useful tool I've found is Image>Adjustments>Exposure> Gamma Correction, and Mate, if I'm trying to teach you how to suck eggs, I humbly apologise.
