Diffuse reflection nebula.
IC 444 is a diffuse reflection nebula directly adjacent to the much better known "Jellyfish Nebula" (IC 443). The area has a shadowy existence next to the dominant supernova remnant, but deserves to be shown as the main actor. The luminosity is not particularly high, so it takes many hours of exposure to get details.
