Yep. That's fantastic!
I'm looking at the antlia 3nm Ha, I've never shot with a 3nm before, but my old astrodon 6.5nm almost completely removed gradients from local light pollution, moon glow would still creep in, but my backgrounds when the moon was over 50⁰ away from my target were always inky black..
I thought going to 3nm would make the sky even darker.
