Excellent. Now, if only the background could be darkened a bit.

Thanks! There's a bit of background there, mostly hydrogen. I try to keep the background brightness around 800 so it doesn't look too artificial.

Narrowband really does make a difference. Last week, I shot 2 hours of LRGB data, and in the final processed image, there just isn't the same depth.

No, here it's only "slow stretching," I try not to touch the HDR unnecessarily.

I had almost forgotten about this technique. Does it actually work?
