large field around M81-82 bathed in the galactic IFN . The image is voluntary stretched to highlight the volutes of this extremely faint glow caused by the combined light of the stars of the Milky Way reflected and re-emitted by interstellar gas and dust
This image was taken under the dark sky of the Quercy area, in the south of France with other friend astronomers , all members of the AVEX club
During the exposures I have been observing some of the galaxies recorded in that image with my old 20" Obsession telescope.
