I recognized it immediately, because it is one of my wallpapers. I did not even have any difficulty finding the duplicate; I simply searched on the credited name "Westlake", so I worry that whoever chooses these marvelous pictures is/are getting lazy.My sad reaction shows how interesting and entertaining APOD is at other times. I have set up my computer to access APOD anew each morning before I awaken, and the result is often a fascinating subject for discussion, or email to friends, during the ensuing day.
