M82 galaxy in Ursa Major, version 1 (preliminary)

M82
version 1 (preliminary)
This cropped photo of the M82 galaxy was taken by James Foster with a Sky-Watcher 10-inch f/4 Newtonian telescope. Messier 82 (M82), or the Cigar Galaxy, is an edge-on spiral undergoing a massive burst of star formation in its core. These stars are expelling violent winds that are blowing gas and dust out of the galaxy. The only hint of this are fountains of hot (red) hydrogen gas streaming out of its center. Shot by James Foster from Pinon Pines Estates, CA.

M81 and M82 galaxies in Ursa Major, version 2

M81, M82, Holmberg IX dwarf galaxy  and NGC3077
version 2
Four galaxies from bottom to the top going CCW, M82 (with Ha complex), M81(largest spiral), Holmberg IX (dwarf galaxy [blue splotch right of M81]), and NGC 3077 (upper right corner). Shot with the skywatcher 10-inch newtonian at f/4 in the iOptron CEM60 equatorial mount. Exposures made were 462min clear and 588min with 3nm Astrodon H-Alpha filter with the ZWO ASI6200MM and 125min color camera with the ZWO ASI6200MC camera.

The milky nearly white clouds are integrated flux nebulae (IFN).  They are a relatively recently identified astronomical phenomenon. In contrast to the typical known gaseous nebulae within the plane of the Milky Way galaxy, IFNs lie beyond the main body of the galaxy. The term was coined by Steve Mandel who defined them as "high galactic latitude nebula that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way.
