A nitpick on the image Andromeda image: when viewed with telescope and in most images you can find online, the core of the galaxy and the region around the core is much brighter than the outer branches, while on the composite image it looks like the core is dimmed to make the outer branches stand out more. So the actual bright part of the Andromeda, seen with naked eye under dark skies, is much smaller.
