Very nice Dan. Your image truly brings out the ring structure of this barred spiral. I visually observed it over five years ago from my then Bortle 5 backyard using my 12 inch. While it was bright and somewhat large to the eye, I of course could not see the level of detail your fine image reveals. Well done.
