This is an image of M33, a galaxy in the constellation of Triangulum. It is 3.2 million light years away, and is around 61,000 light years across.
It took almost 3 hours total of exposure, spread across a bunch of shorter exposures (12 5 minute exposures for the "luminescence" and 12 3 minute exposures for each of the red, green and blue exposures). These exposures are combined and processed to create the final image.
