Anthony,

Hi Ben,


The oldest cluster (by spectrometry) is Berkely 17 in
Auriga about 05 21 + 30 40, and is currently observable.

This cluster is on my "do now, ASAP" list ... please look for a result
with the first available opportunity on my part (following the eclipse
later this week so as not to have the lunar glare when imaging).


It is not an overwhelming object but is rather ominous
when you consider that it checks out between 10 and 13
billion years in age.

I have done quite a bit of research the past few days in relation to
this project and along the way I have read that it is a toss-up between
Berkeley 17 and NGC 6791 in Lyra. Are you aware of any "definitive"
study between the two or are we stuck with the ambiguity? Berkeley 17
has been estimated to be 10.06 or 10.08 billion years old (depending on
source) whereas NGC 6791 has estimates as high as 10.20 billion yrs old.

Anthony.
