Description

On the nearly 4 hour exposure faint nebulae are visible, which are in line of sight in front of the galaxy. These are large-scale gas and dust nebulae, so-called Integrated Flux Nebula (IFN), first discovered in 2005 by amateur astronomer Steve Mandel. Unlike the usual nebulae, these are located outside the plane of our Milky Way and are not illuminated by a single star, but by the sum of all stars in the Milky Way and shine very weakly.
