The detail is in the details! Lots of detail can be brought out in most galaxy images by judicious use of sharpening. The key is to grab lots of data. This one was revisited after learning a few tricks on how to bring out detail without adding significantly to the noise. Another "easy" target from our location, so every year we add to the "Andromeda Galaxy Subs" bucket, and every year this image gets better because of it.
