Nice example of 2 interacting galaxies NGC 1531 and NGC 1532. NGC 1531 is the smaller dwarf galaxy and NGC 1532 is the larger spiral galaxy. NGC 1532 is also known as Haley's Coronet and is an edge on spiral galaxy located in the constellation Eridanus about 50,000,000 light-years from Earth and has a diameter of around 200,000 light-years, making it larger than the Milky Way.
Anyway, hope ya like it!
