Slowly crunching through the data from Astrofest. This one is M17 taken on the 14th - the only image I captured that night. This one is 18x5mins Lum, 9x5mins each RGB & 5x10mins Ha, all 1x1 with the QSI683ws-8/10" Newt.
Still not sure about the colour balance but using this as my point of reference:
