Taken in the early hours from my suburban backyard. I'm not entirely sure about the colour balance. The field stars have good saturation but it's harder to get any colour into the core. There seems to be a faint halo of yellow/brown stars surrounding the core. Not sure if this is a processing problem or just the difference in composition of the cluster with the brightest stars being blue and the dim ones yellow.
