Hi Craig.
Welcome back. The sky glow of the image can measured as a background pixel count using a CCD image capturing program such as CCDops.
While this is not an absolute value with images that have already been processed, the variation in the background count gives me an idea of how much skyglow can be subtracted without effecting the overall image.
