NGC 7822


From Wikipedia…

NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 parsecs distant, with the younger components aged no more than a few million years.  The complex also includes one of the hottest stars discovered within 1000 parsecs of the Sun, namely BD+66 1673, which is an eclipsing binary system… that exhibits a surface temperature of nearly 45000 Kelvin and a luminosity ~100000 times that of the Sun.

This image was acquired through a 4 inch Takahashi telescope.  A total of 74 fifteen minute LRGB images were stacked to make the final image for a total exposure time of 18.5 hours.
