Joe, Well written blog! Also very impressed with Patrick's Cepheid photo 'in Andromeda'. One question that has always bothered me: How do we know that the star in question is indeed in or very near Andromeda? That is, for example, could it be half way there? When I look at really beautiful photos of Andromeda ( i.e. in SBIG's advertisement by Tony Hallas) it is easy to see clouds of stars but they, for the most part, appear unresolved as individuals. Have I missed some other confirming data? Steve
