Description

Sh2-171 in HaRGB. I intended to try my hand at all RGB and no luminance to test for myself whether or not collecting luminance is truly needed. I suspect it is and that if anything it's value varies by target. Sources on the Web are all over the board on this topic. That being said, I added Ha anyway so I didn't really get to test this (yet)...
