Dear Group,

The oldest (or second oldest) open star cluster in our galaxy is
Berkeley 17 in Auriga with an estimated age of 10.06 billion years.

Anthony,

An exquisite image to say the least with round sharp points
all across the field. Isn't it a real challenge to separate the
true cluster members from the background star points?

Your header declares that the brightest stars are only
16th magnitude. I think that is shortchanging this old fellow
a bit and that figure ought to be revised upward to about
13th. Anyway I don't have any trouble seeing about 15 - 20
members with my 10 in.

Great Work!
