Description

Galaxies M81 & M82 in Ursa Major with most stars removed. The two galaxies appear wrapped in a gauzy network of nebulosity. This is the integrated flux nebula (IFN), it is an extremely faint glow caused by the combined light of the stars of the Milky Way reflected and re-emitted by interstellar gas and dust. It’s most easily seen in images far from the starry plane of the Milky Way. The IFN consists of blue starlight scattered by interstellar dust, as well as red light emitted by interstellar atoms and molecules.

The IFN is so elusive it was not identified until the early 1990s.
CFF-185 & ZWO ASI 6200 camera. 52 x 600 Sec 2x2 binned = 8.6 hours.
