The Integrated Flux Nebula (IFN) is a subtle yet captivating phenomenon that stretches across the night sky, revealing itself as a faint glow in deep-sky astrophotography. Unlike traditional emission or reflection nebulae, the IFN does not emit its own light nor reflect light from nearby stars. Instead, it consists of dust particles scattering and reflecting the light of distant stars, giving rise to a diffuse luminosity that pervades large regions of space.

Named for its integrated flux of scattered starlight, the IFN is often found in regions with relatively low levels of interstellar dust, allowing the faint glow to become visible against the backdrop of the Milky Way. Its presence highlights the vast expanses of dust and gas that permeate our galaxy, serving as a testament to the intricate interplay between stars, dust, and the cosmic environment. Despite its elusive nature, the IFN offers astronomers valuable insights into the distribution of interstellar material and the dynamics of starlight scattering throughout the Milky Way.
