I really appreciate the nice pink / magenta Hydrogen Alpha emission :)
H-alpha isn't pink! It's deep ruby red. I think what you mean is that you appreciate that you're seeing some combination of H-alpha, H-beta, and continuum radiation that is resulting in a pink color.
You are absolutely right Chris! I do go on about it from time to time so I should get the scientific words right. H-alpha is ruby red, H-beta would look blue on it's own, and it's only when they mix, and other parts of the spectrum, that give it's characteristic color. But the color words are too subjective and imprecise to me, pink, magenta, neon-red, etc, I'm not sure which one is best for hydrogen continuum radiation.

When I was young my parents took me to several "science demonstration" type of things at our local university. The chemistry demonstrations with burning and electrifying stuff definitely caught my eye. Maybe that's why I'm drawn to a special color of hydrogen emission, what looks most real to me, apparently others have the opposite opinion, it is certainly subjective, I don't begrudge anyone enjoyment of astrophotography, beautiful photos are beautiful, and that's that.
