Not very broight at all, and I could not make out a definite spiral form. 40mm encompasses the bulk of the cluster, but not its entirety. 40-50 stars of comparative magnitude. Need to move teh scope to see the whole cluster. A few scattered red-tinted stars, but not too many.
Cluster is well spread-out.
Good find using TelRad map I made. Weeping Water, NE OC about 8.0 mag. Approx 35 stars of similar mag. No red stars are easily discerned. Very easy to find, using the TelRad.
