C7 or NGC 2403

I realized that galaxies also need to be photographed with a Hydrogen filter—there's really a lot of it there. I started shooting on 03.04 with the L-Extreme filter while the moon was still huge, then shot on 08.04 with the L-Pro filter, also with moonlight, and finally finished on 10.04 when the moon was no longer visible and shot without a filter.
