Kevin those street lights look like the aliens from War of the Worlds! They certainly are close. What kind of lights are they? If Sodium Vapour or Mercury they could possibly be filtered out. With some of the new low noise cmos cameras it is possible to take many fast subs that prevent sky glow saturation. Have you tried say 20 sec subs on Orion (M42). If you shoot a bunch of those you might get something useful, as Orion is so bright. However with the moon working against you it is probably impossible this week.
Are any of your cameras modded? Ie, do they have the blue cast filter removed? This opens up the camera to much more red light and could make narrowband imaging a possibility with an Ha filter - which would not be subject to most of the street light spectrum pollution.
