I captured this one last week using 10s subs and gain of 50 (unity = 139).
Hot blue stars appeared throughout the cluster, and even a few red ones.
Also light on the stretch and heavy on the saturation helped bring out the colours.

From memory I was using unity gain. There certainly wasn't much in the blue channel.
