Scott, Do you have Scott Ireland's book, Photoshop Astronomy? If not, it really is a "must have." It explains how to set color samples on the image, read the...
Scott, What camera settings did you use? What ISO setting? Did you take it with raws that you can adjust the color ratios with your light pollution filter you...

I'm primarily asking for info from those that dare to image from the city, as I do most of the time. I'm sure that usually you'll get better readings at TDS or...
