This is a very nice cluster at low power. It is a fairly large loose 
cluster that spirals out in arms with about 2 dozen stars from
a red star near it's center. Stars are fairly uniform in brightness,
with the red star the brightest. Did not even try to go higher as it 
would have lost it's "cluster" look with more magnification.
Thanks!
