Most, if not all, of these images are taken during a bright moon.

Hydrogen alpha imaging is collecting specific photons caused by the excitation of hydrogen gas. Since this is the most common element in the universe, and the cause of the glowing of all emission nebulae, it is very prominent and bright in most narrowband images.
