At first glance one might think, is this really a galaxy? but it is a most interesting starburst galaxy which was observed by Chandra for a decade. Really interesting (see the link below). I had fun processing this one even though a bit difficult.
https://chandra.harvard.edu/blog/node/650From Wikipedia - IC 10 is an irregular galaxy in the constellation Cassiopeia. It was discovered by Lewis Swift in 1887 and in 1935 Nicholas Mayall became the first to suggest that the object is extragalactic. Edwin Hubble suspected it might belong to the Local Group of galaxies, but its status remained uncertain for decades. Its membership in the group was finally confirmed in 1996 by direct measurements of its distance based on observations of Cepheids; most estimates place the galaxy 2-3 million light years from Earth, with some estimates ranging from 1.5-4.5 million light years. Despite its closeness, the galaxy is rather difficult to study because it lies near the plane of the Milky Way and is therefore heavily obscured by interstellar matter. The apparent distance between IC 10 and the Andromeda Galaxy is about the same as the apparent distance between the Andromeda Galaxy and the Triangulum Galaxy, which suggests that IC 10 may belong to the M31 subgroup. IC 10 is the only known starburst galaxy in the Local Group of galaxies; it has many more Wolf–Rayet stars
