Messier 81 and 82 surrounded by the Integrated Flux Nebula
The photo shows two very well known galaxies high in the northern sky called Messier 81 and Messier 82. The galaxies are seemingly surrounded by dust clouds, which are actually intergalactic matter made visible by all the starlight coming from the Milky Way, called the Integrated Flux Nebula. It is extremely faint and visible only in some parts of the sky with very long exposure times.
The image was exposed for a total of 13 hours with Chroma LRGB filters, a ZWO ASI2600MM camera, Sky-Watcher Esprit 100ED refractor telescope and an APM Riccardi 0.75x focal reducer.
