Seagull Nebula is hunting in the dark nightsky

I am on the way to collect nebulas with animal names for my lovely grandchildrens.
Just now in my backyard toward south, IC 2177, the seagull nebula is in good position.

DWARF 3 and astonishingly nothing else except stable tripod.
Settings: 260 shots, 30s each, gain 80, Ha Filter, all stacked.
