It's difficult to be sure what you're getting in a city situation. I live on the third floor over and under the lights of downtown Mobile. It's hardly New York, but the light pollution is there. I took multiple shots at different exposures and while I struggled to get a tack sharp moon, I was so pleased that this one gave me a 3D sphere, just as it looked, like it could be plucked from the sky as an orange from a tree, a glowing ornament suspended among the stars.
