Another re-process of my narrowband data from an imaging run late last year, this time part of the "Seagull Nebula" right at the edge of the constellation Monoceros. This is part of a large H II region over 3600 lightyears away from us, and in this field of view, we're looking at clouds of interstellar ionized hydrogen roughly 1000 trillion miles / 1600 trillion kilometers from one side of this image to the other.
